数据多的是，就看你挑哪些来看。大家根据自己情况爱好来生活就好。不勉强自己，更不对他人的选择指指点点。
拿着运动选手的数据往自己身上套，有些抬举自己。即使是狂热运动爱好者，和那些高级专业运动员相比都是小打小闹。
早就有著名的 Mortality amongst participants in Vasaloppet: A classical long-distance ski race in Sweden。
下文有概述：
The findings build on previous results, like a famous analysis of more than 73,000 finishers of the 90-kilometre Vasaloppet ski race in Sweden over the course of a decade. In that study, those who completed the race once had half the risk of dying during the follow-up period compared to the general population; six-time finishers had less than a third of the standard mortality risk.
