Yeah I had cholesterol going over 5.0 clogging an artery which the gp had failed to tell me about. And after the angioplasty put me on drugs that lowered by bp even more giving me little dizzy spells. I came to the conclusion that a recent reduction in intensive activity after years of cycle racing, mountaineering, running led to a build up of cholesterol. Blood not speeding round the body as it was used to. An old friend recently with a similar cycling background had a pacemaker fitted due to a build up of fat after his reduction in aerobic activity.
