Most of the comments about what to eliminate are based on ignorance, and none more so than with the physical demands of sailing.
But the 'best' argument to eliminate sailing has to be the one because the 'wind is doing the propelling'. If you accept that precedent it's going to make a bugger of the winter olympics ! I'm sorry folks, but skiing, ski jumping, bob sleigh, luge, etc have all been eliminated as gravity does the moving.
