Shit, shit, shit
Great fun day today...
As part of my PhD I have to demonstrate for undergrads... Got to demonstrate TENS today. TENS is Transcutaneous Electrical Nerve Stimulation; it can be used to block pain (very useful). It can also be used to provide infotainment (or edutainment (whatever)). Basically the device sends tiny electrical signals to the electrodes, which you can place on the affected area (like your back or whatever).
For the demo it was applied to a volunteers arm and hand (yes people did volunteer, but then they needed to, as marks were given for them demonstrating it... hehe)
Now, it's not like this hurts (I tried it before the class), it tingles a bit, kinda like pins and needles. As you get used to it you can turn up the strength of the electrical pulse, or you could just whack it right up. The problem is that due to the external stimulation it is very hard to keep your hand open... it just keeps trying to close.
And now to the title...
"Shit, Shit, Shit" were the first three words that entered my mind...
Basically I was on my way home and at the top of the stairs went over on my ankle (It didn't hurt, thanks for the concern :) ). Unfortunately I kinda lost my balance and thus stumbled down the next three steps, with my bag trying to pull me even further off balance. Guess you could say I was lucky as I'm still here.
Went to the Gym at Five and finished up about Eight. Paul arrived late because of traffic. All in all a pretty good workout.
