I don't know how rare resistance is, but it seems the real question is about resistance coming and going. Yes, resistance can come and go for individuals over their lifetime. Exposure, or long pe...
The urge to breathe is driven by the CO2 content which is still being produced at the same rate at depth as on the surface. We metabolise the oxygen and produce CO2 as a by-product. In fact at th...

Video the zillions of tiny eclipse images, as the eclipse proceeds, which are produced by the gaps in foliage. Any set of bushes or trees in front of the sun will have the effect of presenting man...
It frustrates me that most of the answers are unfortunate variations of "just put the keys into your pocket" The problem with that suggestion is that most sets of car keys include an electronic co...
The poison ivy plant itself is not what makes people itch. It's an oil called urushiol, which is inside the leaves, stems and roots of the plants. That's why some of the sources I quote below use t...
Basically this is almost the textbook worst case scenario lacking only on not being hurt, completely alone in the dark and bad weather. To summarize the situation you have a piece of rated webbing...
They do make a balloon tire a wide one for bikes just for beach riding. That is the way to go on the beach. Takes a wide rim. See often in the Philippines & bikes made for beach & sand ridd...
Yes wet sand is easier. Start in a low gear and see what works. You want weight back - arms straight and head back. Bigger tires are better. Riding in soft sand is hard. As in difficult ...

Flares ignite at 191 °C (376 °F) and burn as hot as 1,600 °C (2,900 °F). This makes them incredibly dangerous since they are well above the ignition temperature of most flammables found in a fore...
As Chris says in his answer "widest part of a van is about a third of the way up". Everything in his answer is correct. I have slept many nights in a homemade conversion van. If you are sleeping a...
Basing on stretch. Assume 40% or 1.4 stretch. Let x be the distance to the anchor from the ground Let y be the rope out beyond the anchor (free rope) Total rope out = x + y Fall factor would b...
