Weight training 3x week.
Running the dirt roads in barefoot running shoes 3x week.
Eating healthy I mean Hearty.
Drinking Wild Turkey 101 as an disinfectant.
Drinking homemade Kefir to boost gut microbes.
Drinking a mixture of ACV, local honey, Cayenne, Pepper, Turmeric and Fresh Ginger daily to ward off evil spirits and anything else that gets past the Wild Turkey and the Kefir.

So far so good... I rarely wear a mask in public.
