Human Biology 101: You do NOT contract viruses. You produce them.

OP is offering an interesting theory here.....

I see where he's coming from...

I've been "sick" off and on in my life, very rarely in the past 20 years...

when I get 'sick' I just let my body do it's thing and I purge it within a few days

So OP is trying to re-frame it like this:

You being "sick" is just your body doing a clensing, purging garbage, and you should let the body process it instead of trying to "fight" it or interfere with it.

Medical Church is a LOT of b.s. and so are vaccines and "diseases"

So WHY are we getting sick? Environmental, chemical issues I'd suspect is what OP would reply.
