Brother, I was talking to an Anti-Vaxxer, of course did not even have High school diploma, but was lecturing me on heart disease ! lol
As I said, thanks to Internet, everyone is now expert.
I love Biology, if I did not go into Tech, 100% medicine was my 2nd choice, I still read tons , however, not once I give myself permission to even have an opinion on anything medical, I am faaaaarrrr from being at a level to form an opinion, I just read, I leave he opinion and actions to people who have dedicated a lifetime studying these topics.
