I have seen and read about multiple younger and middle age people that are DYING (alot are healthcare workers) from Covid-19...with NO pre-existing conditions, before they got infected. You are correct in your statement that says: "People should take responsibility for their own health and safety. Especially the most vulnerable of us."
Each one of us needs to take extra care not to get infected, or..... to infect anyone else. Like I said before...the economy can be brought back to life...a human life once gone, is gone for good, and is not coming back. When your dead....you are DEAD FOREVER.
