I realized this week, while injured, that booze and exercise provide the same relief, temporarily. Meaning, if you're tense and need to relax a bit, a couple drinks will do the trick. Your body does relax. It does work. But, the problem is that the next day you're a bit lethargic.
Exercise has the opposite effect. When you work out, your body processes the stress. It alleviates the tension, but has the added benefit of your body running off of itself. You feel better as a result. The effects, instead of lethargy, are a calm, slightly euphoric feeling that is natural. You're also inclined to eat better, sleep better, and be a bit more productive.
With an injury this week, I was sort of forced to notice the difference.
