I said ten years from a study[1] adjusting for age and comorbidities of the patients, which got 13 and 11 years for men and women respectively. That study doesn't adjust for the severity of the comorbidities, so I agree it's probably an overestimate. I'd like to see a study that predicts life expectancy using more factors (e.g., long-term care residency), but I'm not aware of one. As to masks, I also agree correct use is a problem. Here (SF Bay Area) the East Asian population seems to use them competently and consistently, but everyone else is hit or miss. I would have liked to see more public education, rather than just the unexplained mandate; but the probability that masks primarily explain East Asia's success in containing the virus seems high enough, and the cost seems low enough, that they seem like a favorable bet to me. I do also think it's quite possible that other factors (e.g., different degrees of pre-existing T cell immunity from other coronaviruses) will turn out to explain that big difference though. 1. https://wellcomeopenresearch.org/articles/5-75 https://wellcomeopenresearch.org/articles/5-75
