“Maybe the reason why free radicals and aging are correlated is because free radical production in the mitochondria (part of the cell) is a stress reaction to the damage of aging,” Hekimi said.
海尅米說：“人們之所以把自由基和衰老聯(lián)系在一起，可能是因爲自由基在線粒躰（細胞的一部分）中産生是人躰對衰老的應激反應。

What makes a free radical so reactive, however, is that unlike most molecules it has an odd number of electrons—and electrons prefer to arrange themselves in pairs.
ECONOMIST: Carbon balls to a radical rescue
On meeting a buckyball, a free radical grabs at the bounty of electrons smeared across the bucky's surface, but cannot break it—so the radical stays stuck to it like a leech.

a molecule that has an extra electron and therefore reacts very easily with other molecules

Free radicals are atoms that contain one or more unpaired electrons. Free radicals are believed to be a cause of aging, heart disease, and some cancers.
