Just to prove that somebody out here is actually paying attention ... the high altitude 'death zone' is above about 8,000 metres. If it were 8,000 feet then there would be an awful lot of people dying on their annual skiing holiday!
yer, they got that one wrong.
it may look long.. Until you have watched it to the end. Then you will think it's way too short!

Brilliant - had me in stiches ... especially the tattoo ...
Now that's a great way to get young people's attention on science ...
Seeing is believing!
Amazing how a small paragraph from a study in the 1950's, taken out of context, has impacted all the way through to today - where we are being sold the idea of drinking water all the time and "keeping hydrated".
The study found most people's bodies need around 1.5L of water per day (most of which we get from our normal food intake [and that's not including drinks]), but if you were not eating or drinking properly for some reason you would need to drink up to 8 glasses of water per day to help compensate.
Just Google "1.5L of water per day" and you'll see it stated as a "fact" referenced all over the place that you should drink this much on top of your normal food and drink intake.
Perhaps it is a conspiracy between water sellers and urinal manufacturers ...
The other thing I found interesting was him saying that the myth of coffee and alcohol dehydrating you is over played. Yes it does pass through your system quicker but you do still get hydrated by it. Water is still good for you, especially if not from a plastic container, but the amount you need seems highly overstated.

It's educational & very funny.
I suggest the full bridge rectifier & what's the killer? current or voltage?
As featured in the BBC Click programme recently - LINK. I was particularly amused by the facial recognition software on the electronic door lock on Spencer Kelly's hotel room refusing him entry when he was busting to get to his toilet!
