likely as not the benefits of getting sunshine and producing vitamin D has more to do with joggers longevity than the exercise itself... time of day of sun exposure is a big factor When the sun is elevated about 50 degrees you get more UVB producing vitamin D relative to UVA that damages skin. Along the Central Coast of California currently that's at 9:20am and 2:30pm or so, fifteen minutes at those times of day will be good for a person.. Joggers are going to go out when it's a little cooler and get a worse quality of sunlight, perhaps if they just sunned twice a day in the optimum fashion they would live nearly as long?
Yeah...until Rennick runs you down with his 40 ft RV!
Joggers may live longer because only thin people can jog, and thin peoples live longer.
