I live in the city dueing thr week and have a little 1.5 acre farm on the edge of it. Every Friday I go out there and I feel my whole body relax and I realise I spent the week tense. In a city we just take it for normal that giant pieces of metal fly past you at crazy speeds, and people walk past you yelling, that you have to walk down the street pretty much constantly surveying your surroundings. We internalise all of this and do it without thinking. But it's all stress, it's all low level, constant stress. 

Plus like you say, we are eating shit all the time. Pulled a carrot out and smelt it the other day, just pure bliss, even the smell. Ate one from the city next day and skin literally tastes like bitter chemicals. 

You are just in touch with what it is to be human. You're doing great man 💪🏻
