Well how they are distributed is also important IMO. If you kill one young person for every 10 elderly you save that's a clear tradeoff situation. I don't know what the right answer is of course but it's not as though lockdowns are cost free as some have suggested.

Keep in mind, it isn’t obvious that killing more of their parents and grandparents would lower deaths of despair in youth — Covid itself is (IMO) depressing, not just lockdown measures.
