You do everything you can. You use antibacterial gel on your hands. You keep your hands away from your eyes, ears, nose and mouth. You don’t put stuff in your mouth. You stay away from anyone who appears to be sick.
But, you get the flu or a bad cold anyway. Why oh why?
It’s because many virus and bacterial species, once sneezed or coughed out of someone’s body, have a half-life of 10 minutes, but can still hang around and infect you for a whopping 45 minutes.
You think you’re home free, but then, you unwittingly walk through a cloud of droplets with bacteria and you’re done for.
You can’t protect yourself against every bug. All you really have control over is your diet, exercise, sleep and general life outlook. Avoid smoking, excessive alcohol and obviously, illegal drugs.
If you do get sick, stay home and rest until you’re better. Don’t spread it around.
