Used to do this back in my U.S.M.C. Days. Two or Three of us, ands tied behind out backs, naked except for the dog-tags plastered against our muscled chest by sweat. If I breathed hand and fast enough, I could get a slight visible heartbeat going just under my left pec. I'd watch sweat trickle over my pecs, down my ribs, and over my abs, my chest heaving, and belly tight, and my hands squeezing my gluts. At the sound of fire, three spears of heat travel through my chest, each one piercing a different love of my rapidly beating heart. I'd let out a groan and go down on one knee, chest out and body tight, as I struggled to breathe. As I grew weaker, Stepp would fall onto my chest, as he died - he liked his through his belly-button, his ear on my chest, listening to the last of my Proud and Pounding Texas heartbeats.
