Hi Tobias,
Many thanks for your reply.
You raise an excellent point, particularly in my case, as I spent an inordinate amount of time in sedentary activities such as being on the computer, and playing guitar.
It is a shame that my interests and passions are all ones which do not involve exercising (although I was thinking about it today).
I have the means, but not yet the will. However, I know from past experience that I can get back into excercising.
Thanks again.
