One more reason I overwinter in Bonaire, N.A.   No snow to shovel. :-)

That ought to be good for a 50% reduction (relative reduction, not absolute) in potential heart attack.

After all if in 100,000 people that shovel snow and 100,000 that don't, the ones that do shovel have 2 heart attacks and the ones that don't shovel snow have 1 heart attack, that is a 50% relative reduction. Even if the absolute reduction is.......... well, meaningless.

That is the way drug companies keep score. I should be able to also.  :-)   ;-)
