So, you know how a very sheltered child can be more sensative to disturbing scenes or bad situations... and, a very lethargic person can pull a muscle and hurt themselves if they do minimal amounts of labor? well, my question is, can our stomachs and immune system work kinda the same way? i watch what i eat very carefully, i always use hand sanitizer and wash my hands alot. i use lysol, hardly ever prepare raw meat, wash veggies real good, disinfect everything, etc etc. however, i suffer from more stomach aches than most people i know. could my very strict attitude be causing me to be more sensative to things normal carefree people have become used to? like a little bacteria, etc.
