I'm also 59 (almost 60, actually) and my MHR is 202 (measured). RHR is 60. And refractory time (to get from MHR to RHR) depends on the exercise, but it's typically 2 minutes at rest. Like the NYT article says, MHR formulas need to be re-examined. The only way to really, honestly, truly get an individual's MHR is to measure it in the lab.
