Of course I always think it's good to remember now and then that probably 90% or more of the world's active bicycle riders are neither leisure OR competitive riders- but are riding their bikes for basic transportation and for transporting things. Few of those people ride with their handlebars lower than their saddles- they ride mostly upright and they really lay on the miles on a daily basis. These are serious bike riders, not leisure riders (as most of us actually are).
Good point. It occurred to me later I should have asterisked the whole spiel with some reference to this referring to traditional roadie positions. Frankly, I think if people are happy with their positions and loving their bikes, regardless of what style of riding they do, then there is definitely nothing to "fix."
