iain Posted March 25, 2003 Share Posted March 25, 2003 gravity fluctuates based on the density of material beneath the surface as well. If you're a real hardman you'll go cragging above some galena deposits Quote Link to comment Share on other sites More sharing options...
Norman_Clyde Posted March 25, 2003 Share Posted March 25, 2003 Gravity at the poles is greater, because the earth's surface is closer at the poles to the center of mass. This effect even alters the passage of time very slightly. I will need to look at my physics and astronomy books to make sure, but the theory of relativity shows that time passes more slowly in the presence of a gravitational field. So if you spend enough years at the poles, you may live longer. Or maybe it will just seem longer. Quote Link to comment Share on other sites More sharing options...
ryland_moore Posted March 25, 2003 Share Posted March 25, 2003 Ah, but my geology is still with me! PbS ie, Lead sulfide. However, I do not know of many lead veins to be climbed in the midwest like Kansas and Missouri! Quote Link to comment Share on other sites More sharing options...

Therefore you should head to Chimborazo, on the Equator, where you will be orbiting faster than anyone else on the planet if you want to live longer.

iain Posted March 25, 2003 Share Posted March 25, 2003 or better yet, head to Yosemite and jump off half dome repeatedly. Quote Link to comment Share on other sites More sharing options...
Dru Posted March 25, 2003 Share Posted March 25, 2003 Hey Ryland the Atacama desert in N chile, Bolivia etc. is temperate/subtropical dry belt, same latitude S that N hemisphere deserts are N (more or less). Â Â as for the time dilation thing: gravity is higher at the poles but velocity is lower (smaller circle around axis of rotation) so it probably cancels out. Â anyway lets not forget the whole solar system is moving at 33 km/sec towards Mu Hercules. that's even faster than Dan Howett and his dog on Rainier!

Dru Posted March 25, 2003 Share Posted March 25, 2003 heres what always bothers me about time travel stories, if you move through time but not space, youre gonna end up floating in the vacuum somewhere cause the Earth wasnt in the same place back then.

Dru Posted April 3, 2003 Share Posted April 3, 2003 here's a link to some chinese science on fat loss at altitude Quote Link to comment Share on other sites More sharing options...
Bug Posted April 7, 2003 Author Share Posted April 7, 2003 Dru said: here's a link to some chinese science on fat loss at altitude This article does not address the question of when the body starts decreasing the number of fat cells vs. just shrinking them. I have no trouble losing weight. Eat less run more. The problem is that I still have the fat cells and they pop right back to plumpness with even a hint of laziness. This is why it is so much harder for us fat people to lose weight and keep it off than it is for people who have never been over weight to keep it off. I am still looking for a used copy of 'High Altitude Medicine and Physiology'. Then I will document my claims. $98 from Amazon is the best price I've found so far.

Dru Posted April 8, 2003 Share Posted April 8, 2003 i heard it is impossible to "eat" or get rid of, a fat cell. they just deflate and inflate. Â try liposuction. Quote Link to comment Share on other sites More sharing options...
JayB Posted April 8, 2003 Share Posted April 8, 2003 What Dru said. Â It's all about energy balance, amigo. Keep the energy expenditure up or the consumption down.

Â try liposuction. righto. liposuction and climbing at or above 19000' are supposed to be the only ways to eliminate fat cells as apposed to shrinking them. I think you are catching on.

Terminal_Gravity Posted April 24, 2003 Share Posted April 24, 2003 Bug, I think you are on to something...open a liposuction clinic at 19,000 ft. Â BTW, where did you get your stat of 18,900' for Orizaba? I think you are deluding your self. I have seen eles from 18,400 ish to 18,700 but expect it is acctually on the lower side. I got a good 4 satalitte fix from the summit and it was just shy of 18 5. And for what little it is worth; it felt like a little over 17.

Self delusion is my specialty. 18900 was what another guy told me. Maybe I was talking to myself but it was on the internet so it must be true. Anyway, it's out due to it's small summit. I will be back on Denali within the next two years. Hopefully, I will be able to get above 19000 a couple times. I'll do the WR with friends then, conditions permitting, I will do the upper W Rib. Thanks for the info. Quote Link to comment Share on other sites More sharing options...
