The adage "What doesn't kill you makes you stronger" has never been more relevant to me.

A couple of weeks ago, my brother and I were chatting about how cancer has changed my outlook on life. I mentioned I must have the mindset that my cancer will return someday and, as a result, I must prepare myself both physically and mentally.

He was a bit shocked by my mindset, so I further explained: I must be vigilant about looking for signs of cancer and proactively do whatever I can to make my mind and body strong and resiliant. Thus, if the cancer returns, I will be prepared for the battle.

Part of this is getting into shape. My body's current shape is rather pear-like, and I was not particularly motivated to change that prior to having cancer. Now that I've gone through the fight of my life - quite literally - I must do something about that because I must be prepared to wage war against the cancer that lurks around the corner.

A bonus of this attitude is lowering my risk for heart disease, diabetes and other hazards of people with my girth. It also will mean a more energetic and enjoyable life, one I hope lasts a long time.

"In other words," my brother said, "cancer might just end up saving your life."

Exactly. Who would have thought that would be the case?
