I have been told that many people just care less about their appearance as they get older. Maybe it is to do with maturity or being in relationships. I personally take better care of myself now that I am older but I wear makeup a lot less often.

A lot of reasons, which many have stated already. However, I am 51, and people say I look 35. I think that what's in the heart is most important.

Could be a medical issue such as a hormone imbalance or depression (which might be linked to low levels of neurotransmitters such as GABA) which is probably a lot more common than any of us realize. People shouldn't be so quick to make snap judgements.

At age 66 one's range of motion is limited and 24/7 pain is a key factor .

Work, stress etc

As people get old they are no longer able to work out and keep their bodies in shape. I used to run every day and loved it. It got to the point I just couldn't do it anymore. It was to painful. I am a very clean person take several showers a day so I think their is no excuse for being dirty and stinky. And if you watch what you eat their is no excuse for being gross and fat. However their are people who suffer from things like diabetes and other not so fun diseases that can't do any thing about it. So I would say the whole being in shape and having the perfect body is a young person s thing. When you get old it no longer matters at all. You realize what is really important.

It might be a "why bother?" response to their perceived deterioration in looks, and/or it might be that they lack the energy to put extra effort into their appearance. 🤔

If it's minor stuff, it's wisdom. If it's major stuff, it's pain and / or dementia.

I think its many things. Depression could be one reason, not giving a shit another. The ones that interest me are the ones that still look good. They have a decent body, decent face, but the women don't wear even a little make-up any more, don't get their hair styled and the men wear pony-tails and sweats. I think those people have realized that life isn't all about appearances. They are too busy living a full life to worry about what they look like and what other people think.

Perhaps old people think they don't need attention of anyone anymore

I haven't. I work harder the older I get!

Yes major depression

They are so use to the shit they receive from others day after day and basically have reached the stage of not giving a shit anymore. They are hurting big time and this is their way of showing it.

oh?

this is news.
