you know that scene on Just Visiting when Jean Reno plays a French Lord Chavlier knight who is transported to Contemporary Manhattan? He leaves the museum, and is confronted by leaf blowers, cars, street sweepers, etc etc. They quickly run back into the museum.
Well this is daily life in Shanghai. especially on sundays during market. And this is a small neighrborhood!! oddly skit over to Hong Kong, or even Macau, people live an idylic existance of slow paced walking, that supports one of the highest Life expectancy, but in Zhuhai (the chinese city attached to Macao). It's WORSE than Shanghai, because the roads haven't been repaired in what 30 years, and down to the gravel (from the tar), and they still drive like this here. Wakka Wakka Wakka.
My serious answer: everything you described. Being around these sensations are so tiring but so addicting oddly. I'm a pain freak what can I say. I get a pleasant narcotic sedative endorphine rush, and my legs feel like warm jello it's like being in a nice warm hot tub, but that is, if I can endure the chest pain inducing stress. One day my 35 year old heart is just going to explode spraying blood everywhere. this nasal Chinese yelling (when two Chinese moms haggle over 1 RMB discount of a fish already costing 1 RMB (7 cents USD). So I'm going have a heart attack, because I'm started by the sudden violin sounding conversation of Nasal tonals, because some lady wants to sell 7 cents.
I already chewed my fingernail down to the bone, it has trouble healing back, This is why..... my step mom complains that I chew my finger. Well it's her arguing with my dad, for money that he often gives just to shut up that voice. This is what inspires me to chew my nail in the first place. Well no the Flames sucking last year from FIRST place to last place on a losing streak did that.
But then I often just become catatonic, with a Stotic expression, when I'm in resting mode. If I can't sleep, on the bus, on the train, waiting for things, line ups I go into Nirvana mode. Where I just stare forward. People wave their hands infront of me. oh well. That's their ignorance.
