What Sitting All Day Does to Your Brain and Body | Keith Diaz | TED

Exercise scientist Keith Diaz argues that being highly sedentary is toxic, and that a daily workout cannot cover for a still day. The average adult now sits or is idle 187 days a year, and even elite bodies unravel fast: three days of bed rest costs athletes about 20 percent of their aerobic fitness, and 40 days ages a healthy heart like 50 years. His fix is small and frequent movement, since muscle is a metabolic sponge for blood sugar that dries out when idle. His lab found a five minute walk every half hour cut the post meal blood sugar spike by about 60 percent, and when 20,000 people tried movement breaks, they stayed for how it made them feel, energized and clear instead of drained.

The Art of Reading Minds | Oz Pearlman | TED

Mentalist Oz Pearlman opens by throwing away his own billing: he cannot read minds, he reads people, and he narrates every read as he makes it. He picks three strangers with a clap test, calls one of them as thinking of a dead man from the absence of warmth and the hands lingering in his pockets, then lands on Alexander the Great off a first name too long to count and a confused reaction to the words last name. Halfway through he stops performing and hands the room the only part of the craft that transfers: you never forget a name, you never knew it, because at the moment it was said you were composing your reply. His fix is lifted from the back of a shampoo bottle, listen, repeat, reply, with three ways to reply that pin a name in place, one of which he cheerfully admits is a lie. The finale removes him from the reveal entirely, using an 87 cent Frisbee with a 1.5 star review thrown blind into the audience to pick the stranger who says the name out loud.
