Have you ever said to yourself "Self, you really need to get more exercise." And then answered yourself "Yes, you do, but how can you possibly have time with all this house work you have to do?"
Fellow selfs, fret no longer. The trick is to simply choose the right sort of work.
I tested this theory today, a beautiful late summer day in New England. For a half hour, I attacked a variety of overgrown trees and weeds with my handles, shovel and bow saw. During that half hour, I checked my pulse. The result: within a short time I was into the target heart zone for a woman my age -- 120 bpm -- with a peak rate of 160 bpm.
So now I'm fit as a fiddle and the bushes in front of the big bedroom look much better.
