What major changes do men want to and do make in their midlife and onward in their years?

What are the main drivers for these changes that men make in their lives? Is it related to improving health, sex, self-image, increasing salary, etc.

Do men develop closer relationships with other men when they get older? Or are they tired of hearing other guys complain? Do they feel comfortable talking to and hanging out with many guys several decades younger than they?

Do much older men feel more physically vulnerable..to attacks, thefts, when they are frailer? Or they don't feel this, until something happens to them?

For latter, I do think this might be where women differ alot than men, for the whole of their lifespan is in the area of personal safety.
