why not?

Why not? I paddle about 12hrs a week. If I always did scheduled training irrespective of the weather my time of exposure to lightening would be quite high (we get a lot of lightening in central Florida especially since I live where the seabreeze collision happens most often) and the risk of dieing due to strike relative to all the other things in life would increase. Time of exposure matters. Back when I lived in the Shenandoah valley I could be outside everyday all day and be exposed to less lightening than I am down here just walking to and from my car.

Down here, lightening is much more likely to kill you than wind (at least with our summer storms, winter thunderstorms that are associated with frontal systems and mid-latitude cyclones are a different beast).

The numbers of weather deaths in general are vanishingly small compared to car accidents but there aren't that many people knocking about in severe weather while just about everybody is hurtling down the road everyday.
