Dearest Hitchcockologists,

As a sheepy I of course luff heights.....

Look here I am hanging about bat-style very high up a tree about to pounce on a blokes head. I'm not bothered by the height and that is a tall tree !...almost twenty feet !...now that's high !!



Me...an astounding twenty feet up and not bothered at all !



Take a look at this...






woo !!









Although this person is only looking down about ten feet he is suffering a severe case of vertigo !..he's all dizzy and wants to throw up !


why's that then ?

why does looking over a high edge/precipice make ewe dizzy and stuff ?



I want to know because I am about to play YES's album 'Close To The Edge' to a friend and I need to know if I should warn him about some counter-indications !


whajafink ?




hugs and shmishes


mwah mwah mwah


Neil

The further away the ground is the less the binocular disparity : the visual cues which tell you about your motion (parallax) become less.
You then have to rely more on the vestibular system to tell you about your motion, which in some people isn't up to the job on its own (i.e. without the visual cues).

When the vestibular system  is confused (aka dizziness) it can trigger vomiting, (e.g. car sickness), due to a my-dizzyness-may-have-been-caused-by-swallowing-poisonous-substance-better-eject-the-contents-of-stomach-as-it-could-contain-more-poison reflex.

Better off with Grandmaster flash ...

OOooooooer.......

Just looking at that pic has made me feel quite...... quite  .

I can get a bout of verdigris reading 'Wuthering Heights'!!! I know what your saying, 'surely you mean vertigo'. Well I know what I mean, and I mean 'verdigris'.... yep, I turn green.

Thanks RD as always for your detailed insight. As always very helpful info....I have Grandmaster Flash playing as I type this..and I have to say...akin to Don1....I'm also echoing his verdigris sentiment ! :-)...actually...it's not that bad !

Vertigo and Verdigris.....quite a vulnerable combination !
