> I'm around the 50th floor

In one #hotel in #NYC, I was on the 41st floor when we had a fire alarm go off. I admit that I grabbed both computer backpacks (personal and $EMPLOYER), but after heading down 40 floors, I was wiped out for the rest of the night and also the next day.

In the US, at least, they shut off the elevators during a fire alarm, so your choices are (1) walk down the stairs until you reach the bottom or (2) stay where you are and hope you don't die. Well, there is a 3rd choice: walk downstairs, but not all the way. But you need to get below the floor with the fire _and_ hope that the upper floors don't collapse.

I don't know what the answer is, but high rises need a better escape plan than that.

(Another factor in New York is that many buildings are pretty old, so they don't have modern structural improvements. I'm assuming, but cannot be sure, that most of #Hong_Kong's taller buildings are somewhat newer and likely to have some structural improvements over older buildings. Also, in #Manhattan, #Brooklyn, and possibly other boroughs of New York, some buildings are built so close together that they touch their neighbors.)
