9. Avoid Working Night Shifts

Denmark has classified nighttime shift work as a carcinogen – a cancer causing agent. This is because it interferes with all the biological processes we evolved over millions of years to be active during the day and sleepy at night. Nighttime shift workers are far more likely to succumb to cravings for cigarettes and alcohol, and overwhelmingly choose carbohydrate-dense meals to healthier alternative – partly because their body is trying against itself to stay awake, and partly because healthy options don’t tend to be available at 1 o’clock in the morning.
