Doing the old soft shoe..
I was born at the beginning of the forties, a month before Pearl Harbor, but when much of the world was already dealing with war.
Diphtheria worry and tuberculosis and poliomyelitis (I had two classmates who died of polio) were the thing in the US, but cholera, typhus, on and on, were prevalent elsewhere. Malaria they're still working on, resistant tb too. Back then, measles, whooping cough, scarlet fever (I had it) were ordinary. I had a cousin die of measles, at 43.
Meantime, most of my friends when I was a beginning adult wanted to explore. I've early peace corps acquaintances/friends/relatives. They just took their shots.
I took mine, before the first bacteriology path class, not like theirs, when they went to africa for two years.
Travel is a concept in itself. Many travelers are out there to look around, and at the back of their minds trouble may happen, but they will have been on an adventure to them, living and looking, and they'll perhaps not be nonchalant, but fatalistic about setting forth. A2k's Mathis, for example. Algys, Dag, many others. Mame. Remember J B, the chinese guy? He was brave, in a way. Realjohnboy walked the walk.
Taking airplanes to ensured safety is, to me, not always travel, it's vacationizing. Not that I haven't ever done that.
On the other side, it is not dumb to worry about the health of your children.
I may be wrong again and we're facing a virulent pandemic of pan flu.
I think it comes down to how you live life and there are points for various sides on that. Your family/friends are cautious, Linkat. Seems like a cautious choice would be smart if you all want to get together.
