I'm 46. 39 was the difficult age for me. The worst was 29, but 39 was the next hardest.
For my 40th birthday and everyone since then, I celebrate in my own special way. I do something very out-of-the ordinary and it becomes incredibly life-affirming for me. One year it was sky-diving. Another year I took a motorcycle safety class and bought myself a motorcycle.
It started with an exotic sushi selection at a beach side restaurant in Ventura at midnight and took off from there.
This year I considered a tatoo, permanent makeup, nude sunbathing. I really wanted to do a long motorcycle ride for the weekend but was injured a few months earlier and was grounded for a few months. I ended up with dinner out with 3 friends and then of to the driving range at the golf course near my new home. We were terrible but had a great time. The golf lessons (which was the real gift to myself and amongst my 3 friends) were postponed and will begin this month (January '07) - we hope.

I have a friend that goes out of state to a spa every year with 5 friends. They've done that for about 12 years running.
While a spa trip sounds great, I am really enjoying the 'new experience' for my birthday gift to myself. It's nearly time to start thinking about what I want to do this year...
