It may sound silly, but it’s really a good question, because weightlessness does make a visit to the latrine a tricky proposition.

这个问题听起来可能有些可笑，但这的确是个现实的问题，失重导致上厕所成为棘手难题。

Weightlessness poses two main problems in the bathroom.

在失重状态下上厕所会面临两个问题。

The first is that an astronaut could drift away from the bowl at any time.

首先是宇航员随时可能会飘离便池。

But, there is a simple solution. They put on thigh and foot restraints in order to go to the john!

不过，有个简单的解决办法。为了上厕所，他们将大腿和双脚固定起来。

The second dilemma is a bit more complicated.

第二个问题更加复杂。

Here on earth, gravity assures that our waste falls downward, away from the body.

在地球上，重力可以保证排泄物下坠，完全远离人体。

But, under weightless conditions, body waste has the disconcerting tendency to hover close to wherever it exited the body.

而在失重的状态下，排泄物离开人体后漂浮在四周，还可能会靠近其他东西，令人不安！
