At what point in history did youth/beauty become more important than age-wisdom?

I think back in the early 2000s, lol. It's true because I don't think that the beauty thing happened in the 90s. It wasn't as hyped up about it as it is now. Our society is always changing and something like this seems so useless and unimportant. Maybe age and wisdom will become favored again in 5 to 10 years.

A case of supply and demand, thinks I all the best urban

It comes and goes, like most things. The French were big on it for centuries, around the same time the British puritans were stamping on any kind of aesthetic sense or anything fun. The Ancient Greeks thought both were laudable. When did the shift occur? Every day, back and forth, for some considerable time. It didn't become an 'issue' until the media realised it would sell. I might add, in many tribal societies, the elderly were tossed out of the house to die of exposure, and were lucky if their limbs weren't broken first. I'm thinking Inuit particularly here.

There is a weird trend, people research their symptoms online and when they go to the doctor they will insist they have whatever disease they found on the internet, and will doctor-hop until they find someone who agrees. People don't take advice from trained professionals, so why would they look up to someone with life experience? Beauty has always been important in cultures across the globe, but you are right insofar as our focus on it now is unhealthy. But people can access information from all over the world, and feel they are experts in subjects they are clearly NOT, so of course they don't respect traits like wisdom and life experience.
