One hour+ commute, enough time to prep and eat or go out and eat food, enough time at night to not go bed right after eating, not good for your health, squeeze in an hour of exercise per day, a tiny bit of social interaction with friends and/or family, equals less than 8 (some times even less than 7) hours of sleep. And over the long term for most people 6 hours a night results in sleep deprivation.
But some are lucky genetic mutants. I am not one of them.
Genuinely curious: How much of the sleep deprivation is due to employment practices, and how much is due to, say, American cultural values? Are we sleeping less because our employers or our social lives demand more?
