Put Down the Pink Dumbbell
So, ladies, let’s first put down the two-pound, pink dumbbells. We have been sold a false story about fitness, health (and its connection to weight loss).
I was exercised by wolves. And I’m going to tell you all the secrets and tricks I learned by avoiding the fitness-industrial complex.
Most of what I’ll say applies to men, but I have discovered that most of the outrageously wrong advice is given to women. [...]
So, here: truth number one. Very few of us consider strength-training as essential exercise, but it is. It is especially crucial as one ages, because a natural part of the aging process is losing muscle. Women, especially, need to lift weights, and the trick to lifting weights is stressing muscles. And that weight has to be a real weight, progressively increased, and barring health issues, an average woman should not even bother with two pound weights because that won’t stress your muscles enough to benefit you.
Exercise industry is surely partially to blame for why people don’t exercise regularly: they promise the wrong thing (weight loss) and then don’t push/guide people to do the right thing.

Zeynep Tufekci: Machine intelligence makes human morals more important | TED Talk | TED.com
Machine intelligence is here, and we're already using it to make subjective decisions. But the complex way AI grows and improves makes it hard to understand and even harder to control. In this cautionary talk, techno-sociologist Zeynep Tufekci explains how intelligent machines can fail in ways that don't fit human error patterns — and in ways we won't expect or be prepared for. "We cannot outsource our responsibilities to machines," she says. "We must hold on ever tighter to human values and human ethics."
