Why are old people/hobos, subject of art a lot of the times?

I see a lot of photographers having fondness for taking a portrait like pictures of wrinkled old people or homeless people. Why?

Their faces are interesting. Their lives are etched in the wrinkles and creases of their faces, they tell a story of what their joys and sorrows, their dreams acquired and dreams lost.

Because their image often promotes thoughts about their life story!

Good photos often do that....

Because their faces have 'more to say' than younger ones.

They have so much character in their faces, it tells stories. It's fascinating thinking of where each line came from, what may have happened in their history that caused them to be where they are now. I think their some of the most beautiful :>

i think that od ppl and hobos are the subjects of art a lot bcuz they can be interesting ppl. i mean, so can normal ppl but old ppl have a lot of knowledge and thats wut ppl think, and hobos are usually old, so...ya. pick me for best plz

Those faces have so much character and wisdom that they shine like a beacon to anyone who has a handle on life!

Because their faces have very clear details. They quickly convey character and spark interest.
