Regular health checks (a.k.a routine visits) are probably the bane of many a primary care physician’s existence. I can’t imagine many things more boring than running through a standardized list of questions with a patient who feels absolutely fine, then going through a list of lab values that are almost invariably within the normal reference range, and finally topping it off with a perfunctory physical … Read more

There are lots of studies showing that exercise has many and varied health benefits, from improving muscle strength and balance, to decreasing the risk of fractures and delaying the onset of … Read more
