參考譯文

近年來的一項(xiàng)發(fā)覺表明男人造血的力量不如女人強(qiáng)。這使得外科手術(shù)對(duì)男人來說風(fēng)險(xiǎn)更大。另外由于他們呼吸的頻率沒有女性高，男人需要更多氧氣。但男人的呼吸更深，這樣他們又多了一樣危急?？諝獗晃廴緯r(shí)他們會(huì)吸入更多的空氣。

男人的骨骼比女人的大而且構(gòu)造也不同。女人走路會(huì)招來許多口哨聲是由于骨骼結(jié)構(gòu)的緣由。男人肩膀?qū)掦y骨窄，這使他可以大步前進(jìn)而沒有多余的動(dòng)作。女人的骨盆更寬是為了孕育后代，這迫使她每走一步都得做更大的動(dòng)作，結(jié)果走路時(shí)就顯得有點(diǎn)搖搖擺擺。

假如你覺得男人英勇，由于他能爬上梯子清潔排水檐溝，那么不要忘了這活對(duì)男人來說比對(duì)女人要簡單些。女人的大腿和膝蓋相接的角度使得攀登對(duì)她來說很困難，不論是爬梯子，爬樓梯還是爬山。

男人的皮膚比女人的厚而且不如女人的皮膚松軟，這有效地阻擋了陽光輻射穿過，這就是男人不像女人那樣簡單起皺紋的緣由。女人有一層薄薄的皮下脂肪，比男人多的這一點(diǎn)脂肪貯存有它的用處。它無形中起著毛皮外套的作用，使女人在冬天里感覺更加暖和。女人在夏天里也更涼快。由于這層脂肪有助于隔絕熱量。男人的脂肪分布不勻稱。而且他們沒有那層皮下脂肪。事實(shí)上，他們的脂肪比女人少得多，但肌肉比女人多。男人身體的41%是肌肉，相比之下女人只有35%的肌肉，這意味著男人有更大的力氣。說到力氣，幾乎男人的體重的90%都有力氣，而女人相應(yīng)的比例是大約50%。

肌肉比脂肪的比例大使男人更簡單減肥。為了維持自身能量，一磅肌肉比一磅脂肪多燃燒5個(gè)卡路里。所以當(dāng)男人想要減肥時(shí)，他的體重下降得更快。盡管男人肌肉發(fā)達(dá)，他們?nèi)鄙倥藫碛械哪芰績?chǔ)備。他們的爆發(fā)力強(qiáng)，但是女人身體各處貯藏的脂肪可以供應(yīng)豐富的能量儲(chǔ)備，這是男人所不具備的。

阿拉巴馬高校的`心臟病學(xué)家對(duì)從事繁重工作的健康婦女做了測試后發(fā)覺隨著時(shí)間消逝女性身體運(yùn)動(dòng)的力量遠(yuǎn)遠(yuǎn)優(yōu)于男性。一個(gè)健康的60歲的婦女可以做的身體運(yùn)動(dòng)能達(dá)到她20歲時(shí)的90%，而一個(gè)60歲的男人的運(yùn)動(dòng)力量只是他20歲時(shí)的60%。.
