Kids' concussions and Lou Gehrig's Disease

I meant to comment on this a few months back - but didn't. Lou Gehrig lives on as a sports icon in part because of his legendary tolerance for pain; he refused to leave games despite injuries that would have sidelined others for weeks.

Now researchers are asking whether Gehrig's refusal to acknowledge injury - and not Lou Gehrig's Disease - might have contributed to his death.

Youth football coaches, take note.
