A lot of mustachian techniques depend on being active, energetic, and strong. Those things can get harder with age. I'm starting to think that some seeming lies I've heard turn out not to be lies once you get older and less flexible. For example, here are some things that were never true for me as a youngster but either are true now or I suspect they might become true soon:
* Lift with your legs, not your back (prevents back problems)
* Always warm up and cool down before doing aerobic exercise (prevents strains and tears)
* Replace running shoes regularly (prevents plantar fasciitis)
* Sleep at least 8 hours a day (lets you be more energetic and a better thinker)
* Wear shoes with ankle support (prevents sprained ankles)
* Maybe I should learn to roll when I fall, too.
* Vitamin deficiencies build up, too.
Any more? Any thoughts?
