But does age warrant a new set of guidelines?
Samsung’s Galaxy S21 is going to arrive surprisingly soon and not only has Samsung now confirmed the new models, we now also know they will have stunning new designs.
First up is Samsung, which was good enough to confirm the Galaxy S21 for the first time after the company submitted the phone for certification through China’s public 3C certification program. The certification confirms its model number is ‘SM-G9910’, the Galaxy S20’s model number is ‘SM-G981.
Next comes the juicy part. Famed smartphone leaker Steve Hemmerstoffer (aka @OnLeaks) has spilled the motherlode on his profile at new social network Voice. Across four separate posts, Hemmerstoffer has revealed Samsung’s new designs for the Galaxy S21, the Galaxy S21 Ultra as well as 360 degree videos of both phones. And there’s a lot to like.
The most eye-catching change is Samsung will equip the range with radically overhauled camera housings which subtly mold into the side of each phone. It’s unlike anything I have seen in smartphone design and looks stunning. That said, the Galaxy S21 Ultra camera housing is massive, taking up almost half the width of the phone, and it fits no less than four cameras plus the flash.
Interestingly, Hemmerstoffer notes that Samsung may fit two zoom cameras and does not rule out S-Pen support (which has been hotly tipped), though neither the Galaxy S21 nor the S21 Ultra have a dedicated slot for an S-Pen in their leaked designs.
In addition to this, Hemmerstoffer’s designs show steps both forwards and backwards. The Galaxy S21 Ultra is a big step forward with virtually no bezels, but the Galaxy S21 seems to have thicker (though more symmetrical) bezels than its predecessor. This could mean Samsung is continuing the unpopular policy introduced with the Galaxy Note 20 lineup of downgrading the entry-level model to upsell its more expensive stablemate. I hope not.
In terms of dimensions, Hemmerstoffer reveals that the Galaxy S21 Ultra will have a display of between 6.7 and 6.9-inches (the S20 Ultra uses a 6.9-inch panel) and measures 165.1 x 75.6 x 8.9mm (10.8mm with camera bump) – making it slightly smaller than its predecessor. While the Galaxy S21 matches the S20 with a 6.2-inch display and virtually identical measurements of 151.7 x 71.2 x 7.9mm (9.0mm with camera bump).
And Hemmerstoffer closes by confirming the big news leaked earlier this week: Samsung will indeed step up the launch of these phones by several months. That said, he believes it will be early January rather than December. Either way, Apple’s new iPhone 12 range will face next generation smartphone competition a lot sooner than usual and, given that range has several eye-opening limitations, it’s a good time for Samsung to be more aggressive.

Fitness: Exercise is a golden opportunity for older adults – Sarnia and Lambton County This Week
It used to be that the golden years were all about putting your feet up and taking it easy. But that was before exercise was linked to a reduced risk of chronic disease and increased longevity. Being physically active is now considered a vital component of a long and healthy life, and is especially important for older adults, including those who have yet to jump on the exercise bandwagon.
But there’s no clear consensus as to what type of physical activity is best suited for older populations looking to take advantage of all that exercise has to offer. Is the non-age-specific recommendation of 150 minutes of moderate-intensity exercise or 75 minutes of vigorous exercise a week the best option? Or are there workout routines that offer better results for older exercisers?
A team of researchers set out to get answers by comparing the long- and short-term results of three exercise routines on a large group of Norwegians aged 70 to 77, divided into three groups. The control group (780 people) was asked to follow the national guidelines for physical activity, which in Norway call for 30 minutes of moderate-intensity exercise most days of the week. The second group (387 people) swapped out two days of the general 30-minute workouts for 50 continuous minutes of exercise performed at an intensity equivalent to 70 per cent of their maximum heart rate. The third group (400 people) was also asked to swap out two days a week of the 30-minute workouts, but their routine consisted of four high-intensity intervals of four minutes performed at 90 per cent of their maximum heart rate. Fitness and health data for all three groups, whose average age was 72.8, was collected at the start of the study and again one, three and five years later.
To ensure the two non-control groups stayed on target, they met regularly with professionals who supervised workouts designed to ensure participants exercised in the appropriate training zone, with intensity measured by heart rate monitors and ratings of perceived exertion. Adherence to the exercise routine was analyzed through self-reporting, with anyone who participated in less than 50 per cent of the workouts considered to be non-compliant. At the end of the study, two physicians analyzed the medical data of all three groups, including any deaths, without knowing which exercise routine they followed.
The researchers anticipated that the two groups that exceeded the national recommendations for physical activity would realize an added boost of longevity, but there were no differences in the mortality rate between those who followed the 30-minute general routine and those who didn’t. There was, however, a slight boost in longevity among the high-intensity interval group when compared to the exercisers who performed 50 minutes of continuous moderate-intensity exercise.
The researchers aren’t sure why their hypothesis wasn’t realized, but suspect it had something to do with the overall good health of the study subjects. A whopping 80 per cent reported a medium or high level of physical activity at the start of the study, which suggests that exercise was already contributing to their overall health and longevity. Another finding to consider is that 47 per cent of the exercisers doing the high-intensity interval training stuck with it to the end of the study, compared to the 69 per cent of the controls who kept up their routine for the full five years.
“Participants in the control group did not receive supervised exercise, yet exercised at relatively high levels throughout the five years,” said the researchers.
Another unexpected finding is that peak oxygen uptake, a measure of cardiovascular fitness, showed no age-related decline over the course of the study. This is good news for older exercisers, as a decline in peak oxygen uptake is typical in this age group and is associated with an increased risk of premature death and coronary heart disease.
The bottom line is that there are a number of options for older adults who want to reap all the health benefits physical activity has to offer. It’s also clear that for active older adults, judging the effectiveness of a workout by its length or intensity isn’t a good practice.
“The central implication is that either shorter-duration vigorous physical activity or longer-duration moderate physical activity or a combination of the two, that amount to the same amount of work each week, will have the same favourable health outcomes, with vigorous physical activity being the time-efficient alternative,” stated the researchers.
So go ahead and pick the workout of your choice — or better yet, mix it up between all three routines featured in this study. For older adults, not only does exercise have the potential to mitigate several of the negative health conditions associated with aging, it can truly make the latter decades of life golden.
Apple warns of new iPhone 12 upgrade – The Queens County Citizen
Newly Support document Marked by Macroomers, Apple has quietly warned consumers that there are some significant pitfalls to its innovative new MagSafe wireless charging system, which extends beyond concerns Its weak magnets.
In the range of bullet points at the end of the document, Apple’s Magazine’s warning buyers of iPhone 12 series phones:
- If your iPhone’s battery is “too warm”, say that charging is limited to 80% capacity, increase the heat and limit charging.
- Magnetic strips and RFID chips on credit cards, security badges, passports and key fobs can damage the back of your iPhone and between the MagSafe charger. Apple a Mag Safe Wallet, So be very careful.
- Damages leather cases used with chargers by leaving “circular seals”. There is a similar damage to silicon cases Also reported A few days later, questions should also be asked as to what this does to the glassbacks of the case-less iPhone 12 models over time.
The most obvious fear of accidentally wiping out your credit cards is that the last point (which Apple writes in small gray at the end of the support document) seems to be pressed evenly.
Replacing the damaged iPhone 12 and iPhone 12 Pro rear windows will cost 9,449 (up to $ 50 on the iPhone 11) and 99,549, respectively. Yes you can buy Apple’s AppleCarePlus insurance policy (iPhone 12 – $ 7.99pm / $ 149 upfront; from $ 50.
And the costs continue to rise from here. The same support document says “Your iPhone will charge less quickly [with MagSafe] When using a power adapter that delivers less than 20W ”. Apple never sold the 20W charger with the previous iPhone and the chargers are now removed (Ear pods). So it will be Another $ 20.
Yes, there is a lot to like about MagSafe and as third party tools grow, its potential will be huge. Apple’s warnings around it are important and no one yet knows whether to upgrade to the iPhone 12 model, the second generation Magsafe may want to see if it launches with the iPhone 13 next year.
And, what Apple has About iPhone 13 has already been confirmed, Which is a very wise move.

Apple Issues New iPhone 12 Upgrade Warning – Forbes
In a new support document spotted by MacRumors, Apple has quietly warned users that there are some significant downsides to its innovative new MagSafe wireless charging system, that extend beyond concerns about its weak magnets.
In a series of bullet points at the end of the document, Apple warns buyers of iPhone 12 series phones that MagSafe can:
- Increase heat build up and restrict charging, saying if your iPhone battery gets “too warm” charging will be limited to 80% capacity.
- Damage the magnetic strips and RFID chips in credit cards, security badges, passports and key fobs if they come between the back of your iPhone and the MagSafe charger. Apple sells a MagSafe Wallet, so be very careful.
- Damage leather cases used with the charger by leaving “circular imprints”. Similar damage to silicon cases has also been reported after just a few days, so questions must also be asked about what this will do to the glass backs of case-less iPhone 12 models over time.
While accidentally wiping your credit cards is clearly the standout fear for many, the last point (which Apple leaves to the very end of the support document and writes in smaller gray text) seems equally pressing.
Replacing damaged iPhone 12 and iPhone 12 Pro rear glass costs $449 (up $50 on the iPhone 11) and $549 respectively. Yes you can buy Apple’s AppleCarePlus insurance policy (iPhone 12 – $7.99pm / $149 upfront; iPhone 12 Pro – $11.49pm / $219 upfront), but wear and tear won’t be covered, making a MagSafe-compatible case essential and Apple prices them from $50.
And the costs keep mounting from here. The same support document notes that “your iPhone charges less quickly [with MagSafe] when using a power adapter that provides less than 20W”. Apple has never sold a 20W charger with any previous iPhone and chargers are now removed (ditto EarPods). So that’ll be a further $20.
Yes, there’s a lot to like about MagSafe and, as third party accessories increase, its potential is massive. That said, Apple’s warnings around it are significant and anyone still unsure of whether to upgrade to an iPhone 12 model, may just want to see if a second generation of MagSafe launches with the iPhone 13 next year.
And, given what Apple has already confirmed about the iPhone 13, that could be a very smart move indeed.
