As people tend to have birthday each year - and as I know that finding good presents for those upcoming old people is not easy, recurrently - I thought, maybe it's a help to share some ideas, that I stumble upon.
So, the first tip:

The photographer Andrew Zuckerman interviewed 50 humans about their understanding of "wisdom". The interviewees are all a little older, and most of them pretty well-known: Nelson Mandela, Madeleine Albright, Nick Nolte, Dave Brubeck, Desmond Tutu - just to name a few.
I think its a nice collection of statements, and maybe makes the feeling of getting older a little less negative :)
