I don't mean the expected changes that come with age - such as poor eyesight, hair loss, failing short term memory or poor eyesight.
I mean the odd things that no one told me about, like the inability to put my underpants on without falling over. All my life I have had no difficulty in lifting one leg at a time to slip my pants on in a fully controlled manner. Now for some reason (no matter how hard I concentrate) as soon as I lift one leg up I start to tip over. I have now taken to slumping against a wall just to get my pants on.
When I mentioned this to a couple of friends of similar age to me (I am 58) they said they had exactly the same problem.
Any more examples?
