Good find.
Odd that "back when" the experts cautioned about those over fifty starting up rigorous excersize for fear of injury, and now it is decidedly a major benefit at any age.
Seems that along the way, I would not excersize because that opportunity did not allow the right heartbeats per minute at the right duration. Now. adding walking brisly when able, if even from the parking lot, is deemed beneficial and with cumulative affect.
Getting back into using bicycling for all the many benefits at age 55, has me wondering why I ever stopped.
