For other people following along -- the second link is a direct response to the video I posted by someone who seems to specifically work doing strength training with older people; definitely worth watching if you want an alternate view. The first link seems to be in response to a podcast by Andrew Huberman (sp?) about back pain, which also contains some comments about McGill in general; but nothing directly about what he says in the video I posted. People might find it interesting in its own right but not as directly relevant to the question of deadlifts in older people.
