Aging: It's Not What You Think | Thad Polk | TEDxUofM

[@conscious3714]

As a man of 84 I could not quite understand the technical points of his talk but it makes me more hopeful of my memory when he concludes his speech with 'aging is a kind of transformation rather than deterioration' Thanks.

[@mikesully110]

well if you can grasp a computer and youtube at the age of 84 then i would say you are doing much better than the majority of 84 years olds, most of them round by me are baffled by a modern TV

Aging is adaptation to our environment through time, I think of it as a frozen lake, it will not freeze in a day, but when it's cold for many days it will, that's how our bodies are being changed, "frozen" over time.

My great aunt was born in the late 1800's but in 1975 I asked a question during her favorite TV show. When a commercial came on., she finally answered the question. It was then I realized her 'Rolodex' was simply huge. She answered the question in HER time, not mine. Her mind was fine into her 90's. She was briefly distracted by a device that was invented in her mid-age time of life but I might have used my misplaced and WRONG judgement in estimating her cognitive ability.

Fascinating way of looking at the brain and aging. Love how he explains what an fMRI is - never quite heard it put that simply!

[@jessikapiche6097]

your brain start losing cells at about 30's and continue onward. You could use that to say 'old is bad'. But we have so many cells in that brain that it doesn't really mean anything. I know people who are old and boring at a very young age, and old people who are funny, open minded, original and have opinions in life that make them young and inspiring. Life intelligence is in your heart, not so much in your head.

My concern with his findings is, that he did not talk about the general differences in education of today and the past. Furthermore he did not say something about the general biography of the test subjects. Those who you used their brains in their 70s might have done so already in their 20s. We just didnt have the technical tools to measure it. So my point is, were lacking a really time series. Because we cant say wether there is a decline or not for an individual as long as we didnt monitor the individual. Sorry bad english, typing down quickly

[@olexandrvovchok2384]

Alleggs M. You have a point but investigation cannot last 60 years xd. And does it matter if tasks are primitive?

[@almi6342]

Olexandr Vovchok may be wont need to - but it is at least mandatory to look at the biography of the test subjects. This may give hints .. but some things also need time to proof

[@letsfightaging8119]

we don't have to test individual through his life, that's just way to inefficient, but that's why we are using power of numbers, togetherness to compare , extract average etc. and from that come to conclusions and solutions

Those old or aging people who paid enough attention throughout their life and learned their life lessons will have wisdom. Wisdom only comes with an experienced mind. While young people's brain and mind is fresh and able to learn quickly, old people's brain and mind is experienced and therefore wise.

Aging gracefully is about TRANSFORMATION than DETERIORATION. This is why children and youth benefit from having relationship with Grand Parents.Benefit is mutual. Eastern Cultures always respected Wise Elders. Trauma (emotional and physical) may play a role in Alzheimer.

[@arvilmogensen1945]

I am retired. I recall so many people earning more than me. I recall thinking my paltry savings put away each year not amounting to much. The difference in return between investing options amounting to a case or two of beer based on the meagre sum of money I accumulated. From time-to-time conversations with other people about saving for retirement revealed they saved nothing because “the Government can’t let us all starve.” Saving amounts to effort, and foregoing things I wish I had or wished I could give my family. Now 47 years later, I see lots of opportunity produced unequal outcomes.

[@mikesully110]

well I am 32 and luckily so far my thinking is just as good as it was when I was 18 if not better. but then I try to use my brain every day and I have a job that requires logical thought. I think some of these oldies got settled into jobs where they just do things by rote with no thinking required; they then come home and just sit in front of the TV. Is it any wonder their brains turned into mush and they are no longer capable of learning anything new? or for that matter even performing basic tasks? there was the story of a civil servant who had a brain condition where water filled up his cranial cavity, destroying his brain. it had destroyed so much of his brain all that was left was a thin slice down the middle, yet he was still working in some local government job and when they tested his IQ he had the IQ of about a 10 year old child (as he had been in that job for so long he could do it without thinking)

I have long wondered where creativity in older people seems to have fled. I could never write the poetry I wrote in my twenties, I have seen similar things in musicians - their later songs are so tame. Here's a couple examples: Quiet Riot & Country Joe and the Fish - their first two albums killed; the next ones sucked. I suppose you could blame it on drugs - but I have noticed in other fields as well - Anne McCaffery's dragon books were very interesting and then they got really pedestrian - which was followed by her doing plotting and having other writers do the rest. The Summer Queen / Winter Queen by Joan Vinge - both great - now she novelizes movies. The Dune novels had a similar downward spiral as creativity wained - or did the authors simply lose interest? Is this what is happening - the one hemisphere of the brain starts taking over the other - though he doesn't mention this - in his video the right brain ( the logical side) is taking over part of the left - is that the causing the erosion of creativity as people age?G

[@pbassred]

How about:- its more simple than that? Once you transcribe your initial bag of ideas into words, tunes, images, you need to come up with new stuff in a shorter time-frame. That's tough. Then factor in that, as you awareness of other people's ideas grows, you might discard new ideas for being too similar when actually you are the only person who noticed.

[@muckstar23]

because we have youthful optimism, ya get older and start to be jaded ,happens to best of us ...

[@letsfightaging8119]

Aging is also mental change just as biological, people change interest and taste for things over time and it's normal, like teenager wouldn't play with toys, grown man wouldn't go out all time and listen to music as he did when he was a teenager, so I'm very curious what would happen to human if we restore his body to young, where would his mind, mentality, which is not so much connected with biological structure lead to...

[@Cathy-xi8cb]

Wait; aging massively increases the likelihood that you will have one or more than one disease or disorder that directly affects cognitive ability. High B/P, diabetes of both types, Parkinsons, Cancer and it's treatment, depression, drug side effects...I could go on but I don't have to. This man doesn't live in the real world, in which we aren't lab rats. In the real world, as we age these things are massive contributors to functional deficits. I am an occupational therapist, and we help people with daily living tasks. There is no better way to see brain dysfunction that to ask an older client do a familiar daily living task. I don't need an fMRI to tell you things have gone south.
