I need eight hours. But I can't get more than six after a medium to high effort ride, and later in the day I end up having to take a nap of an hour or two to make up for the lost sleep. I find this rather annoying.

Is this just part of getting old? My dad is 75, and that's what he says. I'm not interested in pharmaceutical options, but I'd love to know if anyone has any tricks up their sleeve.
