From Yahoo Sports - Here is my favorite:
Benefit number five:
My multiple sclerosis has caused me to have balance issues, which is another reason I have turned to swimming three times a week. Swimming allows me to work on my balance, which overtime has started to get better. In 2006, just days before I was diagnosed with multiple sclerosis, my balance hit its worst peak to date. I was not able to get out of my hospital bed and walk around, or even make it to the shower. After a few days, I was able to graduate to the use of a walker, and later a cane. I vowed to myself that I would regain my balance and see to it that I never had to feel embarrassed like this ever again.
I asked my doctor what type of exercise would allow me to regain my strength, and he recommended swimming. I have since started back to swimming after a two-year layoff from the sport that I love so much. With my return to the pool I have regained my balance and no longer require the use of a cane on a daily basis.
