Just how clean is "clean"?

i think i'm just starting to have a problem.

i have a toilet sanitizer, and i use it all the time. regardless of dirty toilet seat or not. sometimes, i even lay toilet paper on the seat.

i have a bottle of dettol hand sanitizer, and it's turning into my best friend. i sanitize my hand at least twice every hour.

i have a packet of dettol wipes, and i used it to clean my laptop just now. i read somewhere that a keyboard has much more bacteria than the toilet seat.

i avoid touching handles/poles in public transports or anywhere else.

today, i felt revolted when i had to hold the handle in the train. i only used 2 fingers.

i used my elbow to open the classroom door today.

i went back into the toilet to wash my hand after exiting the toilet door.

i sanitized again.

i think i'm starting to have a problem.
