How are you getting the 50% figure? 1500 people died yesterday, which was more than the day before. That isn't 14 days of declining cases, there haven't been 14 days of declining cases. Sure, the overall trend might be going down, but it isn't a 50% reduction.
I agree with you that a lot can happen in 3 months, but let's not act like any of the decisions about reopening have been based on any data or anything related to the health and safety of Americans.
If you want to go do things, that's cool. Just don't say that your decision is based on anything other than your desire to do that thing. None of these decisions to reopen have been science based.
