Golly that was a very fast - not so aggressive reply, thanks.
For the record I walk 20 minutes down a gorge and back up the other side and back every day to get to the office (no road). Every other day I run 5km in the mountains, the first km goes up 160m. I then do 60 press ups and 60 sit ups. I then follow it by drinking far too much beer. BTW I am 56 this year. Perhaps I should drink more beer or reduce the exercise.
