Are you sure that’s what you want to do?
For the past, I don’t know, say, 300 days I've watched backpackers sleep until the late afternoon, imbibe in horrible diets and, drink, smoke and do drugs. While this may not be the most healthy diet, the fact is, a lot of travelers and backpackers are pretty far from actually being healthy, or caring about things such as health (or personal hygiene). While some people backpack to broaden their perspectives, many travel to get fucked up. The strange thing about this, though, is sometimes they try and do ridiculous feats of physical strength, in the midst of being drunken sloths.
