A: Will drinking lots of water in the day(s) prior to a long trek mean I will need less water on the trek? Your body does not store significant amounts of water (most of the, usable, water in our body is in blood plasma). Unlike energy which can be stored as fat or carbohydrates, water has no real storage mechanism. This is why you will die of thirst long before you die of hunger. As such, once your body... (more) |

A: What are some heavy-duty alternatives to a long line for walking a dog on rugged terrain?
