Have a happy birthday.
At 40 you are definitely over the hill and it is all down from now on. Get to the gym, tone up the muscles. Then you can have some Californian wine just to relax. Forget forums and other annoying distractions.
It is my 90th in August. Not enough energy left to throw a party but hope someone will do it for me. Ten years ago it was a cinch. Hope your next forty years are as good as my 40 - 80 journey.
