Morrisons Miles

the sleepy physicst filled his car with petrol today and went to use the morrison miles card he had inherited from his late gran. sadly the card wasnt working anymore so it had to be replaced and tsp was quite sad to have lost his grans card.
on the up side had an interesting bio lab again today. were looking at breathing and understanding the gas exchange in the lungs. i had to hyperventilate using pure, 100% oxygen and then hold my breath. the pure oxygen meant i could hold it far longer than i could with normal air! quite fun! although all the hyperventilating and holding breath did result in mild dizzyness.
ive been so rubbish at loading my blips in the last week as ive been rather rushed off my feet. still have a couple to put up when i get the chance...if i ever get the chance!
