I was a long distance runner in my 20's Rm
I too was involved in some of these sports in the 1930,40ies,( have a film clip of the long jump, with tabulation done in 1942), soaring off the 10 meter platform, the 15 00 meter races, hitting the wall, the "needles" pain. so, deep interest, fellow feeling here.
Its mostly a contest of human genetics when you think about it.
Rm, yeah, it is amazing how the runners, pole vaulters look like the models that walk the fashion shows. Hope that these fine specimen and speciwomen have more kids than the welfare queens.
