Try to use some type of boiling water technique to invent drinkable sanitary drinking water that doesn’t get me drunk (might not be necessary in some parts of Asia)

Most parts of the world that is not North America: try to convince some wealthy persons and bar owners to sponsor me to getting a bunch of bread molds and rats/mice, possibly even pigs, to conduct antibiotics and vaccine research, otherwise I might die from random sources…

Not sure if I could reasonably do those given my limited biology knowledge, but I guess they are worth trying. Besides that I’d just try to be less blunt/offensive so I don’t get sent to jail and try to live my best life I guess
