10. Stop Smoking and Drink Less

Drinking damages the immune system, spikes sugar levels and kills the liver. Smoking causes all sorts of things from plaque build up in blood vessels to a number of illnesses.

If this holds true, remember that second hand smoke is a danger to those around you so if you’re going to light up, make sure to do it in a well ventilated area.
