Ah ha! Thought I'd aged since coming on GN. Now I realise it's not the stress of dodging the bullets the juxtaposition of balancing new and exciting differences of opinion, but rather the evil rays from using my iPad in bed.
I'll just stand on my head and do a bit of jumping on a trampoline then - oops! - forgot I have to walk with a stick! - and have .......pick anything from a long list of aging musculo-skeletal and balance problems.
Part of the art of aging is accepting what you have gracefully and concentrating on what you can do rather than hankering after youth. These are just different phases of life and are the natural order of things; just as youth has both up and downsides, so does aging - embrace it all with a smile!
Had a look at that link. Scepticism aroused immediately by the fact that "BT" and "lifestyle" are in the url. Scanned the article. Scepticism confirmed.
