We're at that point in human history where you have to tell people to walk 20 min a day for "benefits". It's so depressing I don't even know where to begin with, it's bellow the bare minimum I'd expect for a 70+ years old Dedicating even 5 hours of your week for real vigorous activities will absolutely change your life. Is the baseline really "do just enough to not die of an heart attack before 50" ? So much wasted potential...
