So even if you have more slow-twitch muscles consuming more fat, then does this affect Caloric Intake Restriction in regards to lifespan?
Will more slow-twitch fibers allow you to take in more calories with less adverse effect on longevity?
If muscle fibers can keep multiplying even during old age (even old people can increase their muscle mass) then does that mean they have different/longer telomeres, that don't run down as quickly?
