When I was hiking the Pacific Crest Trail I spent 3 months at a time (others spend up to 6 months) as basically an unwashed, sweaty, stinky person. The funny thing is that we hikers could not really smell each other. Maybe a few were really rank (I had a friend I begged to please get his feet wet because his socks were killing me and I had to stay at least 20 feet behind him), but mostly we didn't notice each others' smell. Nothing was worse than the smell of a day hiker. We could literally smell them coming a mile away. The smell of fabric softener, deodorant, shampoo and all that was so overwhelming and it really was offensive to all of us. We'd talk about this a lot.
The amount of sugar, salt and artificial flavors in foods has been shown to have been deliberately calculated to stimulate us to consume more. It is both very satisfying and not satisfying. The perfect combo to turn on our little rat brains to keep pressing the lever.
