Definitely I think the possibilities of happening of above is ridiculous, but as you mentioned, what-if thoughts is recurring and around me, so I am hanging in there again, and before that, I was in a nightmare during my trip to
Japan, e.g. what if my
Japan friend infected me because he kisses my head ( just for greeting), what if I infected hiv because of hot spring in Japan, so you should know how suffering for this travel.
