Exercise, endorphines and love

For some or other funny reason, opiates, both laboratory- and body-produced, make me absolutely love my spouse and my kids. Or rather, perhaps endorphines (the opiates I encounter outside a hospital) just sorta strip away some pretense, and leave me "bare" as it were. Anyway, to make a long story short, every time I exercise with any intensity, I feel the love I have for my family ever more intensely. Yet another reason to exercise. God, I feel so blessed.
