this thing, monitors your heart rate, steps, sleep pattern. it's designed for yuppies who think wearing it can kick you into action.

back in 1989, when i was 19, i bought a heart rate monitoring watch by Casio for ~$250. You wear a strap with electrodes on your chest, and it transmits to the watch your heart beat. I wore it 24/7, for like 5 years. I was to become a borg. But today, no thanks.
