Cabin fever

Our county 'Shelter-in-place' order has been extended through May 3 (the previous order would have ended April 7) . Schools are closed until May 1, but rumour has it there will be an official announcement cancelling school for the rest of the year. I don't understand why we have these end dates at all - are they based on actual evidence? Or is it just psychological - to give people the feeling there is light at the end of the tunnel. And it is so confusing - the Governor has issued an indefinite stay-at-home order. One would think the orders from Governor of California would outweigh the County order, but why then does the County issue new orders? I read somewhere, can't find where now, that if the guidelines are confusing or have conflicts, people are less likely to adhere to them. The new order from the county is actually very clear - it specifically bans going to any public recreational facility (parks, tennis courts, playgrounds, etc.), it limits any kind of game...
