I don't think you can cite one study concerning an increased risk of varicose veins and conclude that exercise is not all it's cracked up to be.

That study seems pretty legit, but it only concerns one health problem, and a relatively minor one at that. Fewer than 2% of the people in the study even required hospitalization for their problem. Comparing that to the numerous benefits of exercise for things like diabetes and heart disease, I think exercise is still a worthwhile use of time.
