    Of course caffeine is bad for you! You start getting all jumpy, and nervous...twitchy to boot.

    I usually dont drink it because of its insomnia producing abilities, but its useful sometimes. Gotta wake up early to actually do stuff, when all your used to doing is waking up at 2pm and lying around? ICED TEA is the answer.

    I was at a business seminar type thing a few weeks ago and on the crunch night caffeine couldn't have come more in handy

    Where do these researchers get their funds to reinvent the wheel? It's been known for a very long time that caffeine stimulates the CNS and in particular, irritates the sensory cortex increasing alertness and mental reactivity. Obviously, if you are under stress that increase in mental reactivity will be an increase in reactivity to stress.
    It's also not news that caffeine stimulates cardiac muscle and is both a positive chronotroph (sic; see below) and inotroph (sic, see below).

    I've looked up the terms "chronotroph" and "inotroph" on several online medical dictionaries with no matches so far... can you enlighten me on what these mean?

    Thanks,

    It means I've made a spelling mistake, two in fact, those should have been "chronotrope" and "inotrope". Sorry about that!

    A positive chronotrope is something that makes your heart beat faster. A positive inotrope is something that makes your heart beat harder, i.e. greater, more forceful contraction of the cardiac muscles.
