Trying to Stay Away From the Sickness

I hope that everyone is doing well, and that you've been avoiding the sickness. Even if you haven't gotten your flu shots, hopefully you're still jumping and jovial. 

I'm trying my best to not get sick, especially since a lot of people around me are getting sick. I need to go some herbal teas, and what not. 

Then I regret not going to the gym for the past 2 weeks. That usually keeps my immune system up.

Do you have any methods, or techniques to avoid getting sick?

If so, what are they?
