I don't care what the doctors know! I will not let fear run my life.
Seriously?!? Without trying to sound rude, then you are being foolish. We have lost 2 friends to the virus. My wife is a Hospitalist (doc who works only in a hospital) and she treats covid patients on a daily basis. Without going into all the numbers and details, you REALLY should wear a mask when in ALL public enclosed areas and yes that means no dine-in restaurants. She has treated patients aged 21 to 85. Typically, the older you are the more likely you are to die. If you don't die, most have severe lingering effects (hard to breathe, very lethargic, etc.) that are very slow to recover and some have not yet who had it in late February. Some are asymptomatic (usually the younger). Those with underlying conditions (diabetes, overweight, etc.) have a much greater chance of dying.
Taking precautions is not fear. You cross the street at crosswalks with a green light so as not to get killed by a car hopefully. That is a reasonable precaution. The green light does not guarantee you will not be killed but it greatly reduces the chance. However, walking on across the intersection when you get to the intersection because you won't let a light decide when you should walk is pure foolishness.
It really is not that big of a deal to wear a mask. Yes, it totally sucks. Yes, I really do not like them or being told I should wear one. But would you rather wear a mask when in an enclosed public area and most likely not get sick or would you rather continue to be free and potentially get sick and possibly get your wife (and/or others) sick because of your choice? This is not some theoretical question. This is potentially a true life and death question and you should seriously consider the pros and cons.
BTW, have your nurse friends actually been tested? The vast majority of healthcare workers are not been tested so they could have it and not know. To me, not testing healthcare workers is also foolish but that is another issue.
Regardless of your choice, I hope you stay healthy.
