I always try to keep fit through eating and exercise. I don't actually exercise much as I have a physical job. They say that you should exercise enough to make you heart beat faster, such as rowing, cycling, running etc. Well, my heart beats faster every time I go up a ladder (to bedroom height), so I consider I get enough. Last week, out of interest I decided to keep a log of how many times I climb a ladder to bedroom height, so this does not include half ladders and flat roofs. I only worked three days this week and not full days: Mon 31, Tues 55, Wed 32. doesn't sound too bad, but when you say 118 times in three days, not bad for a 67 year old. I'm going to continue keeping check to see what is the most and average.
