Does that mean you have a "caustic" personality, Spitty? OR.........you may be a super hero in disguise that does not know of his super power to turn metal to degrading rust upon your touch. that would be cool. Rustman!!!
Working at his mild manner job of sheet metal fabrication guy, only to hark the call of evildoers and turn their weapons to useless red powder with a mere touch of his gifted hands.

Seriously, some people have minor added increase one way or the other of the pH balance of their body with a balance of acid and alkaline, if one or the other is a little too high, the body adjusts itself to maintain a perfect balance of 7.0. Your body may swing past the neutral depending on your diet and digestion of foods at times to contribute to your superpower, and I do not think you are alone with these common pH level swings or powers.
