It's trying to burst out of the top of your head. At -5, -6 you start bursting blood vessels in your eyes and your nose and the pressure of the blood in your brain is fantastically painful. Lots of guys have died pushing -8 onwards when something lets go and they have a big bleed on the brain.
Negative g is really quite unpleasant.
Yeah, you can just imagine, can't you? You wake up floating outside, you've píssed your space suit (as ever), you can't get the lads to wake up and let you back in and then, when you eventually do, in the depths of your hangover you realise you've drunk the next six months' worth in one weekend.
You'll never be a proper centre-forward then.
I'd love to go into space but nt sure how my vertigo would cope with it.
