I take the stairs, I believe humanity as a race is becoming too sedentary, too lazy, reliant on machinery. It won't be long until we're experiencing a wall-e type situation, a few hundred years maybe.
Healthy? Well lets see, overweight, high fat high salt diet, past hard drug use, current soft drug use, rampant alcoholism, smoked 40 a day for a decade (although I rarely smoke now), what else, oh yeah, I have huge stress problems. It's remarkable I have lived this long, nonetheless I reserve my right to have an opinion on the way humanity is going.
