So, the place I live, it's in a large overpopulated metropolitan. The parking area is basically the road and it always had a strong stench of urine and remnants of cowdung, but today due to faulty sewers fecal matter had overflown onto the road and of c, no one had cleaned it. It's a deadend road so the only people stepping on it are people who live here, but I had to take care of my Motorbike there and had to clean it properly, so I could see stuff on my tires and while splashing the tires with water, I might have gotten a bit of stuff on my legs.

I felt deeply disgusted of my situation, but I felt scared of catching something as I am often exposed to stuff like this. The rented hotel I lived in has foot prints on the lift doors and it smelled of saliva and was painted red by marks of chweable tobacco product. The interesting thing is, I pay a premium to live in this place as every other place I went to smelled of sweat and piss (inside the rooms, this is outside, my room is neat and clean)

P.S: I sprayed isopropyl alcohol on everything I had touched just to sanitize it. But, isopropyl alcohol is apparently toxic and I am not supposed to use it frequently, what shall I do?

How can I keep myself safe and sane in this environment?
