Stupendously hilarious "common sense" recommendations from experts who don't get it:

I'll start;

How often have you read an article suggesting that on long airplane flights, you get up and move around the cabin at least once or twice an hour?

1. Easy. Saving for retirement n/t

2. while once or twice an hour is excessive

I thought if you were stuck in your seat on a plane for a long period of time with little movement, you had a risk of blood clots in your legs or something like that?

3. I agree, but to attempt to get out of your seat on a typical airline these days

is just about impossible! Wandering around the cabin is liable to get you decked with a coffee pot!

4. None. On long flights, I pass out.
