I'm in my 50s- and conscious that I'm past the half way mark. I'm full of aches and pains and I don't have any energy. That's the negative. The positive is that I'm not so easily fooled and I don't take myself so seriously. On balance I'm a lot happier. But I fight, fight, fight to keep my mind young. When I start maundering on about the good old days I'll know it's time to die.
