this is the difference - you're comparing two different things. Weighing the benefits to the risks, what will we choose?
1----- Work is essential, we all need to pay our bills,etc, so we MUST find a way to continue working as safely as possible (and then, staying away from others unless taking precautions, b/c the NECESSARY work means possible exposure and consequences)
2---- Play/travel etc is NOT ESSENTIAL. It is fun,and MANY of us love it,but it isn't an essential thing- not at all. I can take a day,relax somewhere near home. Is it as fun as a trip to WDW? NOPE. But a trip to WDW could bring so much damage to others I interact with in my life, that I can easily forgo it for a while.It's a LOT of chances being taken,for something that I don't really NEED.
That to me is the difference.
