I've lived with vegetarians, ok we were in love! Anyway they said you could easily smell a meat eater. There were no smokers in our home, so I tried a pure veggie diet, sauteed,steamed and baked food but no fries or preservatives, alcohol, coffee or strong spices for three months. I was pretty fit by then and healthy too. Bonus! Guess what? They were so right, you can smell a smoker 'a mile off' and meat eaters if they are in the same room.Have you ever had a small child tell you the milk is sour a day before you can taste it? We mess up our sense of taste and smell by eating too much spiced and fried foods, too little raw stuff, and of course smoking and drinking alcohol and coffee. Drive around the town and you will smell a fast food outlet blocks away with your polluted nostrils, imagine what you smell like to a wild animal?
There are many 'primitive' peoples that have bans and taboos around the pre hunt days, including sex. Hormones and pheremones are powerful and a dead giveaway. We are only doing a half job if we wash our gear but fail to manage our own body odours. We have a wild plant here in SA that is known as 'duiweltjie, duiweldooring' or'seep plant', the plant is a magical soap and is odourless, great for washing you, your clothes and everything else -including pots and pans!
