When you reach fifty, by the very nature of the passage of time, whatever you have done with your life, you have experience, and experiences.....this may mean that you can become intolerant of those younger than you, and absorbed in your own life - this may appear boring to others - with regard to being angry, I think this is more the frustration of watching others make the same mistakes you made, and not having learned by yours! By the time you reach sixty, you are much more mellow (believe me!!)
