Can a bird have a heart attack? (They have high blood pressure, just like we do). Cardiovascular disease may be an unfortunate consequence of mammalian evolution. In other words, heart attacks may have evolved as a human survival mechanism, so what kills us today may be what kept our species alive in the past.

During starvation, the body conserves energy by slowing down the function of the vital organs, including the heart, thus preserving available energy and prolonging survival. A protective response to starvation may promote heart failure, because two proteins that team up to conserve energy when food is scarce also limit energy production in the heart–a situation that can prove fatal when the heart is stressed and in need of an energy boost.

There is evolution of a species and there is the evolution of a single human mind, too. We hope 2012 doesn’t see the end of the world OR this website, but we have to deliver a small warning to all our readers and listeners: If we don’t get more support from you, we will be nothing more than a memory in the future.
