^Been a long, strange couple of weeks. Tried out a new cardio
  regeme yesterday - run around at jogging to sprinting speed,
  then when the heart is beating out of my chest, jump in the
  pool, cool off for a few minutes, then do it again. "Dip and
  Run" "Sprint and Swim". Physical fitness is important enough to
  figure out ways to make it fun so that you don't mind doing it.^
