I can't do a temporary "Lotus Positon" without actually breaking my knees.
I did the "Lyke Wake Walk" with ease in the early 80s now climbing the stairs too fast leaves me breathless.

I couldn't do a 5 mile "Fun" run, as in the early 80s without weeks of intensive training.And possibly monkey gland shots.......

Oh, my God !! the list is endless and it's all my fault.

Blimey, mt wife Ann and I jived for about 5 minutes at her 60th birthday party and we both had to sit down and gasp for a while.......
