It's a fact that has to be faced and soon, but international travel, in the way that the west (and east) has been accustomed to, is going to have to slow down if we want to avoid future repercussions, as it's clearly the primary case of transmission on a macro scale, and has pretty much enabled the entire planet to become infected in a month. That's serious. Obviously there are many factors driving this travel apart from cheap flights, which allow lots of people from very average incomes to travel abroad at least once a year and often many, many times a year. The number of Euro-based stag or hen weekends, for example shows it's as easy to go to Prague to get shitfaced as it is to go to Leeds - and it won't take you that much longer to get home either and cheaper than a black cab.
I haven't travelled abroad much recently thanks to caving, but it was a joy to be able to go to California 'regularly' 25 years ago at an easily-affordable price, even for a peasant like me. I'd really like to go to Europe for a trip soon, but with 14 days quarantine it's hardly practical if the trip is only 7 days. Those endless EU-country business trips for one short meeting where you 'may as well' stay over for a night and have some fun in a city that won't remember you. Like a bat out of hell...
But also the wealthier, older group - pensioners, who have all the time in the world, and plenty of money, to travel around the globe on planes quickly, but also for weeks or months at a time on cruise ships. These can export and import viruses in slow-motion, as we've seen, where gradually the whole ship gets infected and no-one can get off, hundreds of miles from dry land, with ports where the locals definitely don't want them now. It was ironic that a vessel designed to be so comfortable that the passengers never want to leave it then became some dystopian prison that the passengers
couldn't leave, even if they wanted to. It's all going to have to be re-thought - until we have a vaccine or everyone who's going to die from it
has died, leaving the immune to have a big party - after the funerals of course, not before.
My dad's old company pension scheme is groaning under the strain of all their ex-employees not dying yet. He earns more than I do a month and he's 83. Many are on endless holidays at sea, but I doubt they spend much money on their brief trips on land. What does an 83 year-old cruiser need to take home as a souvenir? Only themselves now.
In the UK, as in the other countries badly affected, we have shocking states of unfitness in the adult population, with obesity being the most obvious. What's less obvious about obesity in particular, is that lungs don't grow larger as the rest of the body grows larger. So for a guy who should weigh 11 stones but now weighs 15 stones, his lungs are now severely undersized, as all the extra body mass still has to be fed oxygen - from an also-too-small heart, and in blood vessels that will be struggling to cope with the pressure needed to get all the blood around this extra volume and back to his struggling heart. That's before you factor in the poor muscle development from no exercise, ever, and the ever-increasing alcohol consumption, which doesn't help anything really.
The really sad aspect to all this is that many people have died who had underlying illnesses, but that weren't remotely life-threatening to them, thanks to advances in treatments and better care, support and awareness of disability, infirmity or just old age. But add Covid-19 and they just folded, including one of my friends now. Knowing that the lockdown was deliberately delayed (and is now being deliberately prematurely relaxed) to afford political capital to these revolting people is making my blood boil on a daily basis, but that's for the judges to decide eventually. I hope it's a long one.
So that's my answer to the question. Though I may think of more later
