The things everyone should know about time.
關于時間,每個人都該知道的事。
A lifespan is a billion heartbeats.
動物的壽命大約是十億次心跳的時間。
Complex organisms die. Sad though it is in individual cases, it’s a necessary part of the bigger picture; life pushes out the old to make way for the new.
復雜的有機體會死去。對個體來說這是個悲哀的事實,但在更高的層面上這是必須的:舊的總要為新的讓路。
Remarkably, there exist simple scaling laws relating animal metabolism to body mass. Larger animals live longer; but they also metabolize slower, as manifested in slower heart rates.
值得注意的是,自然界存在著關于動物體型和新陳代謝的一套簡單比例法則:體型更大的動物活得更久,但新陳代謝也更慢,表現出來就是心跳會更慢。
These effects cancel out, so that animals from shrews to blue whales have lifespans with just about equal number of heartbeats—about one and a half billion, if you simply must be precise. In that very real sense, all animal species experience“the same amount of time.”At least, until we master #9 and become immortal.
這些效應相互抵消,結果就是從鼩鼱(一種外形似鼠的小型哺乳動物)到藍鯨,各種動物的壽命都差不多是15億次心跳的時間。從這個意義上來說,所有物種都經歷了“相同的時間”——至少是在我們掌握了第9條并獲得永生之前。
