Re: If you were asked ...
Yoga
It is a gentle exercise that is very very good for you, and at the same time you get out and about and meet other people.
I had the chimney swept in this house a few years ago, and the chap who came round was actually retired (but his number was still in the phonebook) ..he was as fit as a fiddle! Told me he does yoga and also pretty much lives off juiced vegetables!
I've been wanting to get into it ever since - just not got the time.
