you get the gut feeling too?
does it hurt?
I get less of a "feeling" and more of a "rumbling" that portends bad things.
Is that what causes my appendix scare to get itchy??
Most likely the same principle.
The repairs are always weaker than the original tissues. Your system can compensate for changes in pressures, but the weakened areas around healed wounds don't deal with it so well. I expect NAKID will get the opportunity to experience that first-hand during his first deployment.
