| BMI in the overweight range but who are very fit. A
| relatively large proportion of their extra mass is muscle
| compared to non-athletes.
|
| This is probably the minority of athletes, though, so it

| taught as a norm. I also don't know how that relates to
| COVID.

| Terry Crews is 6'2" and 245lbs. That's an obese BMI at 30.6.
| Does he look obese to you? Fat is heavy, muscle is even
| heavier, both will cause your BMI to go up. Obviously most
| people don't look like him so really the BMI figure kind of
| stops being useful when you have significant muscle.

| population. (Most people underestimate their body fat
| percentage.)
|
| BMI is accurate enough for a general population risk screening
| tool. We aren't dealing with precise numbers here anyway, just
| approximate ranges with significant differences between the
| results of various research studies.
|
| On an individual level excess body fat is a critical risk
| factor for COVID-19.

| I made my own covid mortality calculations last April, and was
| not scared off by my estimated odds, 1 in 350 per year. Using
| the linked UK calculator my odds were far better than I had
| estimated, about 1 in 16,000 per 90 days.
|
| The activity calculator was interesting, also. I had heard that
| mask-to-mask interactions were based on an hour of nearness
| while indoors. I thought it to be an overreaction when people
| would wear masks outside and cross the street to avoid passing
| on the sidewalk.
|
| So I looked up 10 people with no masks in a room, and it was a
| 1 in 200 chance per hour of catching covid given the odds of
| someone from my area being there who had it. Once again the
| risk was not as high I as thought it would be.
|
| I'm curious what others think of the numbers from these
| calculators, especially those who find them alarming or
| surprising.
