Sucks for you. Look up "predominantly" in the dictionary.
However, as I have said repeatedly, life is risk. It would be awfully hypocritical of me to preach about courage, then turn around and demand that healthy young people destroy the world and embrace unlimited tyranny because I got panicked about a personal risk to myself.
Staying at home is not tyranny. Nor is this about your personal risk.
Lockdowns dont help with thatand probably wont help the old folks in the end.
Lockdowns, if implemented early enough and supported by other measures, can help to slow down the spread, which may be the difference between life and death for a lot of people. If you insist on killing yourself that's your business but you probably shouldn't be making that decision for anyone else.
