I gather that Glenn Reynolds writes the most read blog in the world, though I don’t recall ever visiting it, until now. Regarding today‘s NYT story on calorie restriction he writes:

Calorie restriction is unlikely to work in humans — and I’m not sure it’s worth it anyway — but drugs that mimic its effects are another thing entirely.

If CR is unlikely to “work” (I assume Reynolds means “extend maximum species lifespan” as CR clearly does have immediate health benefits) how does he expect CR mimetics to work? If the effect works then a pill will be worth it for many more people than practice, but that’s another thing entirely.

Fortunately the rest of Reynolds’ post makes perfect sense, so I won’t go on, and may visit again.
