Ha ha there are lots of things that I can no longer do like balancing on one leg.. the latest one is vigorously shaking my head!
I have worn my hair quite long for most of my life and always shaken off excess water after washing it, but now, if I try that I get so dizzy I fall over! (It has happened twice)
If I drink more that two pints of cider it takes two days to recover, my resting pulse has gone up ten beats and I have to take a tablet every day for high cholesterol.... the joys of reaching 60.
I can remember on so many occasions when I sneered at older folk who were slowing down in life... now it is my turn to be teased !
