Thank you all for replying.
Insensitivity to pain: this has been checked into, and apparently, this is due to my Aspergers.
I also can stand quite deep temperatures, but in summertime when temperature rises over 22 degrees, I start to suffer.
My skin on my hands is fairly rough, but when I use battery acid to get the machine grease of my hands (which does not come off with soap), I notice no red skin, nothing.
Hands are in normal shape, even after using the acid few times a day (if the machine had a rough day, and stopped a lot).
As for tolerance to chemicals, my father has this as well, just like me, it's apparently with most family members of my fathers side.
Oddly, this affects only the males, from what I gathered from many accounts.
No doctor/specialist (Hematologist/Neurologist/...) has found out why.
And no, I do not do drugs.
Also, I had to drink water for a while (3 weeks), which was a horrible week for me (used to coffee), and besides a headache from lack of caffeine, I had no other effects of the lack of coffee.
Going back on my coffee, also did not result in any change, physically nor mentally.
Though I understand you making fun of me, might I tell you, Bufofrog and Exchemist:
1) You never met me.
2) You never heard of me.
Thus, it is quite darn impolite to both judge me, and insult me with your jokes and unbelief ...
"Why would acid help with grease?"
This I do not know, but where soap with sandgraines failed, the battery acid does remove that stuff.
Wished I could answer, but I cannot.
"there is no way that healthy tissue would not get damaged."
And yet, I have no known issues?
Besides the above-mentioned, then.
All that aside, does anyone please know the terminology, I am seeking for?
Thank you.
Ben
