What is the age where “negative aging starts?” When does the physical decline start?

What is the age where ???negative aging starts???? When does the physical decline start?

It???s generally accepted that a 20 year old has a higher level of physical fitness, health, and cognitive agility than a 30.

But is there an improvement at age 22? Has a decline at 27?

What about 20 v 25? Or 18 v 20? Or 22 v 27?

If you took a sample 100 million people, and found the mean age where ???the decline??? VERY FIRST begins, what age would you get?

Personally, I think 21 is the first year of decline. By the time you are 6 months away from your 22nd birthday, your physical health, along with fitness and cognitive fluidity, have already started a lifelong decline. Of course you barely notice it, but by 23 you???ve already lost the look of ???true youth???, and by 25 the signs of aging are not so subtle.

By 27 your face has forever lost that ???youthful look???, and you begin to get the face of ???mid-adulthood??? which lasts until mid 40s. You???ve also seen significant loss in fitness, health, immunity, metabolism, fluid intelligence, memory, etc.

I might even say that the absolute peak is 18- this is when health is at its absolute prime, and you???ve reached full development. By 20, you???ve probably gained a little in athletic performance, but you???ve declined slightly in fluid intelligence and health. You???ll also see some 20 year olds showing signs of aging they didn???t have 2 years ago. This is definitely true for me- I???m 3 months away from 21, and I???m already starting to see the decline.

I read somebody say that by 22, they couldn???t do the workouts they used to do at 20- how normal do you think this is.

True enough :) You're right- not every answer needs to have applicable value in order to be relevant, interesting, or worthy of discussion. I rescind the "silly" part of my comment!

What is the point to anything Luckie?.. There is a scientific answer for those who are interested and it is when there is an irreversible impairment of biological function. Organs age at different rates - or rather have different rates of repair. Once the rate of repair and regeneration drops below that of intrinsic and extrinsic damage, that organ begins to decline from its normal range of function.

Aging is an irreversible deterioration. The apoptosis and developmental cycles from gestation to puberty are not aging. There is nothing stupid about this question at all. It challenges what a layperson defines as aging.

Yes. Babies who are born with hair and fingernails have cells that have died, while still in the womb.

I guess you could make an argument for autophagy being positive aging, because it extends longevity.

Technically, aging begins at conception. Which is why all these questions are so stupid.

What is the point to this question? If you were to get a true answer (which is silly in itself) how would you apply this information?

Maybe it's perfectionism...interesting as a hobby, but nothing you can do with it practically...like "how many angels can dance on the age of a pin"....

Roth, there's nothing "magical" about any point estimate of a population. Obviously there is a variance. But, statistically speaking, Stephen is right.

And puberty is a well defined age, isn't it? I don't know why anybody wants to pinpoint the exact age of decline. It's arbitrary and not relevant if you take appropriate action. Though maybe if you're like Stephen "Abs of steel" R. here, you will necessarily decline. If you're at the top there's nowhere to go but down!

Wrong. There's nothing "magical" about 30 years. HGH and testosterone decline after puberty in everyone.

There is no specific age.

Where do folks get these ideas? I've had nearly a dozen of these questions over the last couple months. Some popular magazine article put this idea in folks' heads?

People don't 'age' at the same rates, and to suggest that you can quantify at what point in one person's lifetime (measured in years) that this 'ageing' starts to occur seems quite ridiculous to me. I agree with Stephen that we begin to age the first moment after being born.

This doesn't have to be a negative thing. Fluid intelligence may reduce over time but 'wisdom' will hopefully only grow as one gets older. The only constant thing in life is change. Embrace your impermanence.

Bmd increases till 30, that's also when hgh and testosterone drop off naturally. I think I learned in ap biology though that we start dying as soon as we're born; which makes sense since kids always seem to have more energy and a youthful appearance. So I wouldn't worry so much about aging at 20, you started aging almost 20 years ago!

Interesting way to put it: positive vs negative aging.

There is really no positive aging in biology. There is growth and development and in some cases metamorphosis but aging is always considered as negative given it involves deterioration of function.

You would find most experts on aging would consider that in humans 21 years is around the time that aging begins.

I've been wondering the same thing....am I REALLY still "in my prime" at 25?
