Anyplace can "re-open". (The entire concept of "re-opening" is a gross simplification - used by and for simpletons). Northern Italy or New York City could "re-open" tomorrow. And the graph of deaths would go straight up. But that means nothing to the clowns who were sitting in the back row in math class telling fart jokes because they don't or can't or refuse to understand anything sciencey because it comes from pointy headed intellectuals in the deep state.
Covidiots seem to think that because some places (certainly not Cozumel) have been successful in "flattening the curve" that means it's all over, have a parade, pass around a cigar, whoopie. Flattening the curve (as has been done in Northern Italy and other places) has been accomplished at great sacrifice, and it's a good and necessary first step. But all it means is that the speed with which the virus is currently spreading has slowed. The virus is still there, waiting for fools. We are all still in a very real, very existential crisis. As soon as you stop the social distancing ("open up", for simpletons), then the speed of the infection spread will skyrocket. And then you go back to square one, and you have to stay there (sheltering in your home), with everything closed again, for another extended period maybe a week, a month, 3 months?).
Until there's a safe, effective vaccine (widely available), massive testing, and better understanding of the virus (fer cryin' outloud, we still don't know if having had it and recovered gives you any protection against getting it again!), we are all in an unprecedented crisis - yes, even the deniers, we're all in this together.
Unless you are OK with just giving up, stepping outside, passing around a beer, and shrugging (or denying) the thousands of deaths that will soon result. If you are OK with many thousands of deaths (quite possibly including your own) then be honest about it, and go drink some disinfectant as suggested by stable geniuses.
I would love to see Cozumel and Palau and Bali and Rome and Paris open for tourism again too - as soon as it's safe and responsible to do so. But I don't expect that will be the case this year or much of 2021 either (I'm hoping for Q4 2021 as an optimistic target for the next trip, if all goes well). Yes, I know this is already (and will continue to be) economically devastating to many, many people, especially those who live in places that have become dependent on international tourism. I'm personally suffering greatly from the financial impact of this pandemic, too. And I've lost a loved one to it. So yeah, I get it.
I wish I could book a cheap flight to CZM soon and enjoy some diving, just like everyone else. But I'm enough of a realist to understand why that's not going to happen for a long, long time. Others will figure it out eventually. Well, most will - some will be in denial until they're strapped to a gurney, gasping for breath, and wheeled into an overcrowded hospital and triaged, hoping it doesn't get as bad as things were in Northern Italy so recently.
So sorry you can't go diving for a while. Put on your big boy pants and grow up.
