《汉书·传·司马迁传》
精神用的过分就会枯竭，身体过度劳累就会损坏；精神和身体过早的衰竭，而想与天地共长久，这事还从未听说过。
夫神大用则竭，形大劳则敝；神形蚤衰，欲与天地长久，非所闻也。
If the spirit is used excessively, it will be exhausted; if the body is overworked, it will be damaged. Spirit and body become exhausted too early, trying to last as long as heaven and earth, and this is something that has never been heard of before.
