HeythereandwelcometoLifeNoggin.嗨，大家好，欢迎来到生活小脑袋。

Butwhatifyouspentallyourtimeinthatbed?Whatifyouneverleft?但是，如果你把一生的时间都花在床上会怎样？永远不下床会怎样呢？

Imean,thatmemoryfoamcan'thurtmeright...right?!Ohright,Iknowtheanswer.

我的意思是，记忆床垫总不会伤害我吧...对不对？嗯，我知道答案。

Sadly,itcan.

不管你相不相信，美国太空总署(NASA)曾经付了18,000美元给个家伙，要他躺在床上70天。他们想研究微重力对人体的影响，躺下这么长的时间，模拟长途航程对航天员身体的影响。

Thebedsweretiltedbacksixdegrees,causingthebodilyfluidstoshifttotheupperbody,whichduplicatedsomeoftheeffectsoflow-gravityenvironments.

床向后倾斜6度，导致人体体液移往上半身，而它在复制低重力环境中的某些效应。Afterthe70days,thefirsttimethevolunteerwas

vertical,hisheartratejumpedto150beatsperminute

andfeltlikehewasgoingtocollapse,whichisdefinitelynotgreatforanotherwise-healthyman.

70天之后，志愿者第一次站直，他的心跳达到了每分钟150下，整个人感觉到快要崩溃，对于一个健康的人来说，这绝对不好受。
