24 minutes per mile is WAY different than what you posted earlier. A dead person can do 1.2 miles in 24 minutes.
It seems to be enough to keep me healthy without causing injuries.
That is another fallacy going around that one needs to do hard exercise. Much more important is daily exercise. I see people at the gym running hard on the treadmill, but do not see them again for months. I almost never see any one older than my 80 years in gym.
