I am so happy to be doing some more exercise of late, I had a really horrible couple of weeks of work where I did the bare minimum. It is so very true that exercise is a feel good 'drug'... don't exercise and you suffer withdrawal.
I can believe that appropriate exercise is a powerful tool in addressing certain mood imbalances / disorders. It truly makes you felt alive and 'buzzy' to be active and on the move. I hope that my recent reminder will be enough to keep me from lapsing into inactivity again anytime soon... gotta love that natural high.
