First off, drink water like you’re trying to pass a drug test.
Secondly, avoid sugars and grains(which contain glucose), as their properties inhibit your immune system.
Third, maintain a consistent intake of vitamin C.
Pre-one: keep your vitamin D up! Around 1/3 of some population that was studied had a deficiency in vitamin D, which is responsible for your immune system health, and is primarily attained through UVB exposure. I.e. Direct Sunlight, specific tanning beds, vitamin D supplements. Apparently you can’t get the necessary amount of Vit. D from food alone, so get the skin under the sunlight!
Now for the substance.
Millenials.
Isn’t it counterproductive to take a generation of self-absorbed psychopaths who still think they’re going to change the world and put them all into one category?
