My argument isn't "obviously all the confounds run in this direction". Just we don't know if people who use sildenafil or healthier or less healthy than the general population. I suspect it's a function of age, younger people prescribed sildenafil are probably less healthy than age matched controls, and older people are more healthy than age matched controls.(because they have to be with with it and fit enough to convince someone to have sex with them, and be healthy enough to have sex)
