Rory Gallagher was blood type AB negative. He also abused various substances heavily. Many have suspected a connection between his rare blood type and his sweat being acidic.
Here is an older article of mine:
Ammonia smell when sick
It has been established that rh negative individuals lack the protein functioning as gas channels also responsible for ridding our bodies of toxins.
Hello,
I can at least confirm, that my sweat makes the strings of my guitar black and/or rusty.
A band member always was stunned, what I have done to them.
And my sweat has an unusual smell, when sick.
Also have a missing protein, but don’t know exactly what. It was found out, as I had to use heavy painkiller (morphine) and they didn’t work at all. If, I have to use morphine that gets activated with water, so to say. (hydromorphin)
