They need to and they're doing too. Now we're into the time of post world war old agers born in the 50s and later.

Not all of them are adaptive to change. I have realized that age doesn't really or shouldn't really classify a person as an elder. Some are old and lack the wisdom and patience to learn. Some elders listen though, but listening and being willing to apply the advice given by youths are entirely two different things.
