You hear stories about people performing heroic feats in life-and-death scenarios: lifting a car off of a child, swimming for miles to get back to shore from a shipwreck, etc. Like most middle-aged guys, some part of my brain assumes that I would be able to do the same. A lifetime of living vicariously through action movies and video games leads me to believe that my body is just waiting to be unleashed for its superhero moment, like a Manchurian Candidate of fitness.

But, historically, I have not had many of those experiences in my life, so there is no need for an alter ego, yet. Even if I did, building a heart-healthy lifestyle around life-or-death adventures does not seem sustainable. Unless you fake it.
