And BTW people used to believe that DOMS was from lactic acid buildup, but that turns out to be false.

comment Good books to learn survival?
Excellent, canonical answer. Deep Survival is really good on decision-making, which can be much more important than technical skills.

comment What is the most efficient food to take a for a 12-15 day hiking trip?
@RussellSteen: Last I read there is no place in the US that does not have a potential for Giardia. Domesticated animals, including the increased popularity of hiking with dogs, over the entire US has spread this protozoa to virtually every stream in the continental US. Totally false.

comment What size dry bag is best for keeping and washing clothes?
I don't understand the question. What is a "dry bag" in this context? Why do you want to do this? What do you mean by "travelling, not hiking?"

comment water knot vs figure 8 follow through vs X for rock climbing anchor - What is easiest to untie?
This application is the only reason I know the water knot. When there's a totally, totally standard knot for a certain application, I would need a heck of a good reason to use some other knot.

comment Do polarized sunglasses protect against snow blindess?
@OlinLathrop: Cool info, thanks. I guess the relevant search term is Brewster's law. Note that polarizing filters probably block nearly all of both polarizations of UV -- see outdoors.stackexchange.com/a/7785/2169 .

comment Do polarized sunglasses protect against UV?
@imsodin: The second paragraph is background information on what polarization is, but it doesn't answer the question at all. The third sentence of the first paragraph is written as if it follows logically from the preceding sentence, but it doesn't.

comment Is it safe to put snow in water filtration?
It's generally safe just to scoop snow into your mouth (although it will make you cold). The belief that backcountry water needs to be treated is basically a myth: lightandmatter.com/article/hiking_water.html Since water often comes from snowmelt, clean snow is normally going to be even less likely to need treatment than running water. As noted in the question, you obviously don't want to use snow that looks dirty. I don't know whether the Chlamydomonas nivalis in pink snow is harmful or not: en.wikipedia.org/wiki/Watermelon_snow

comment How can I prevent plantar fasciitis?
I think most of this is wrong. The first paragraph is probably reasonable, although the evidence I've seen correlates PF with obesity, and that doesn't necessarily mean that cutting pack weight will help. The second paragraph seems to promote the misconception that PF is a heel injury caused by heel strikes; it's not a heel injury at all, that's just where your nervous system interprets the pain as coming from. I don't think the final paragraph is supported by any evidence. Physical therapists tend to believe in this sort of stuff, but it's mostly junk science.

comment Can bears smell food inside dry sacks?
This doesn't seem quite right to me. Any airtight container will reduce the amount of smell that gets out, and a bear's nose only has finite sensitivity. An airtight container should definitely reduce the distance from which the bear can smell your food, and that makes it less likely that you'll attract a passing bear. There are thick ziplock bags sold especially for minimizing how much food odor gets out.

comment Stove/fuel setup for harsh conditions
I think your question is thoroughly answered by the accepted answer to the first question you linked to. The answer is a white gas stove.

comment Rappelling in the Rain
This is what dry treated ropes are for. If it's very cold, you also have the possible issue of the rope freezing. For perspective, canyoneers often rappel down through waterfalls. Rock climbing grew out of mountaineering, and it's perfectly normal to encounter bad weather on a mountaineering trip.
