Cut while skydiving will a person bleed faster?

So my buddy and I watched that old Keanu Reeves film Point Break the other night, and we got to talking. We're thinking that more air pressure causes you to bleed at a more furious pace. So if someone's in a knife fight in a plane, is cut, say across the arm, then jumps out of the airplane to parachute to the ground - will they bleed to death before they hit the ground because the air pressure is causing them to bleed so quickly? It doesn't have to be skydiving, it could be on like, Everest. Will you bleed crazy fast higher up? I know that there are a lot of variables here, but I'm just curious if the thinking is sound.

Can I get on the plane with my Casio Pathfinder watch?

Will they take my watch away at the airport? It is digital Casio Pathfinder with a barometer, thermometer, compass, and altimeter. I'm flying in about 6 hours, and I really don't want to lose my watch, but I want to take it with me.

Where the HELL am I?

[GPSFilter] Should I buy a GPS or GPS-enabled phone? I want a GPS unit and I'm also in the market for a new cellphone. The cellphone can wait but I want the GPS now... unless there's a GPS cellphone which fits the bill. (This may be laughably optimistic but I know nothing).

GPS duties:
Used for tracking/navigating hikes and bikes, including trips into the back-country that may last for up to 7 days. (During the winter I tend to spend a lot of time on snowshoes wandering around in forests and it is very easy to get lost. I currently use a compass to basically make it back to where I started, which works pretty well.)

An altimeter would be really useful.

It needs to be totally weatherproof and rugged (i am really hard on equipment).

It needs to be light and small enough that it's not going to bug me if I'm only carrying a hydration pack (this is also why I'd like a cell/GPS combo).

I guess one option is buy both a GPS unit for serious duties AND a GPS phone for less onerous trips.

Cell:
Needs to work reliably pretty much anywhere in the world where there's cell service (currently I have an Ericsson T39 which rocks but is getting reeeely old).
