Cost-Benefit Analysis : 1 Hour of Exercise

Lately I've been reading some books about economics, trying to get a handle on what's happening with the, uh, catastrophic global economic collapse.

When economists try to make a decision, they run a cost/benefit analysis on the subject. So for example, if some citizens are debating whether to vote for a clean-air bill, they need to factor in not only the improved respiratory health savings, but the subsequent rise in rent and land prices as the area becomes more desirable to live in. If the benefit of cleaner air is greater than the cost of higher rent and property taxes, then it's a good idea to vote for the bill.
So, I've been trying to see my actions in this new light, especially as I try to stay motivated to keep exercising.

Being a pretty busy guy, the cost that stings the most is that of time. In a given day, I can spend my time on any number of things; work, eating, hygiene, socializing, entertainment, meditation, or exercise. What happens when we run some cost/benefit models on these options?

The baseline cost is an hour of my time. So, if I do work, I lose an hour, but gain a certain amount of production which can be used to further my goals. If I watch TV, my gain is perhaps a few laughs and some relaxation.

However, it's important to remember that in both situations, the benefit is far from certain. I might get something useful done during the work time, or I might spin my wheels ineffectively. The same with TV. While I often enjoy good programs, just as often I finish watching something and feel less energetic and like it wasn't "worth" the time. All this plus the hidden health cost of sitting in a sedentary state for an hour, which I discussed a few weeks ago.

Compare this to exercising and getting a workout in. The cost is still the same, an hour, but the benefits are guaranteed. If you're exercising, you will burn calories and build muscle 100% of the time. There's no maybe about it. And if you keep going and eat well, there's a similar 100% outcome of looking and feeling better.

The relatively low cost of an hour of my time vs. the guaranteed result of a healthier body is a no-brainer, at least on paper. Of course in the real world you have to struggle against your own excuses, lethargy and desire for the easy way out.

Taking this logical, Spock-like approach to the problem takes some of the wind out of your mental protestations and can be a powerful motivator. When something makes absolute sense it gets harder to fool yourself into thinking you shouldn't be doing it.
