    ...Morgan found again that brain chemistry makes a big difference. The amount of neuropeptide Y you pump is closely connected to your success—the more, the better. Morgan also found that the best underwater navigators release a lot of a natural steroid called DHEA, which buffers the effects of the stress hormone cortisol and helps the brain's hippocampus with spatial relationships and memory. Divers with the most NPY and DHEA graduated at the top of the class. Those with the lowest amounts did poorly.

    At POW camp and dive school, Morgan has discovered a simple and accurate way of predicting who will survive and perform the best under extreme stress. You might call it the telltale heart. It starts with something called heart-rate variability, or HRV, the variations between beats. Healthy people have a lot of variability in the intervals between their beats, with their tickers speeding up and slowing down all the time.

    It turns out that the best survivors don't have a lot of heart-rate variability. Instead, they've got "metronomic heartbeats"—their hearts thump steadily like metronomes—with almost no variability between beats. That is, the intervals between the beats are evenly spaced...
