Immune systems, work like this?

slipss

So about your immune system. You know the way that if someone is isolated from other people and then are introduced into the general populace (or however its spelt) that they are more susceptible to disease, like that american president that contracted polio, but does it mean that say, for example, if you ate your dinner off the street since you were about 5 and didn't die that you would have an immune system more capable of fighting bacteria?

Well, if you're living on the street you're going to be deficient in a whole lot of nutrients, and that nutrients you are getting are probably being sucked out of you by worms. So, no.... your immune system would probably be in bits. But I'm not a doctor, someone correct me!

there'd be plusses and minus'

on the plus regualr bacteria wouldnt hurt you but you'd probably have no minerals which would kill you or lead to more permanent diseases.

its like an alcoholic. it takes many drinks for him to get drunk (a plus ?) but he has a raped liver (a minus)
