Do people experience adrenaline differently?  I've never been a fan of
"extreme sports" (I hated each and every parachute jump I made, and only made
6 because I paid for all up front, and was going to get my money's worth,
damnit).

Yesterday evening I decided to inject myself "a mano".  Normally I use a
little spring-loaded contraption called "betaject" that I just hold against my
skin and then press a button.  But that seemed like a dependency on a machine
that I didn't really need.

So I injected myself, and it was surprisingly easy (unlike the machine, which
gives you a jolt, it didn't actually hurt at all - the needle must be vey
fine).

But immediately afterwards, nervous coward that I am, I was swamped with an
adrenaline rush.  Almost fainted.  Nauseous.  Sweated like a pig.  And,
curiously, almost crapped myself.  Ended up crawling (couldn't walk) to the
bathroom, so I could take a shit.

It was just like food poisnong.

How can anyone enjoy that?  It's just not possible.  So either people
says.

Will try again Saturday - assume it will be easier now I know it doesn't
hurt.  On the other hand, I knew parachuting didn't kill me...

That wasn't adrenaline, apparently.  It's the Vasovagal Response
