Butwhatifyouspentallyourtimeinthatbed?Whatifyouneverleft?但是，如果你把一生的時間都花在床上會怎樣？永遠不下床會怎樣呢？

不管你相不相信，美國太空總署(NASA)曾經(jīng)付了18,000美元給個家伙，要他躺在床上70天。他們想研究微重力對人體的影響，躺下這么長的時間，模擬長途航程對航天員身體的影響。

Thebedsweretiltedbacksixdegrees,causingthebodilyfluidstoshifttotheupperbody,whichduplicatedsomeoftheeffectsoflow-gravityenvironments.

床向后傾斜6度，導致人體體液移往上半身，而它在復制低重力環(huán)境中的某些效應。Afterthe70days,thefirsttimethevolunteerwas

andfeltlikehewasgoingtocollapse,whichisdefinitelynotgreatforanotherwise-healthyman.

70天之后，志愿者第一次站直，他的心跳達到了每分鐘150下，整個人感覺到快要崩潰，對于一個健康的人來說，這絕對不好受。
