Isn't "number of old men who die from heart attacks while doing anything is non zero"?

It’s the going from zero to 100 that gets folks it seems.

Deep, heavy, wet snow is called heart attack snow for a reason. It sneaks up on you - a driveway you just cleared for years with normal snowfalls is all of a sudden a 10x workout from usual, and your brain doesn’t completely process this. Anything else at that level of intensity would likely trigger you to take breaks.

That said - I think inactivity is far worse. But I still make a point to go shovel my elderly neighbors walks here in Chicago before they have a chance to do it when we get particularly deep snowfalls.

Shoveling snow is a well-established high risk factor for older adults.
