Orkhepaj: btw how does getting vaccine shot makes people happy? :O
Some (generally speaking, I mean....not anyone in particular) think they're saving the world/humanity by getting it & feel good about doing so, or are glad they can finally do more things(a number of countries afaik block some activities/things or make life more difficult if you don't get it), etc.
Me? I'm happy that I haven't been vaccinated. I am young enough and healthy enough that my risk of getting very sick is very low, and i'd rather do my best to distance and sanitize than risk some of the(albeit rare) side effects like clotting/etc, or even the nasty feelings some seem to get from the jabs.
Addition: I am also glad that all my fellow goggers who got the jab seemed to suffer little ill effects from it, and can now have a bit more freedom/peace of mind as a result
