數據多的是，就看你挑哪些來看。大家根據自己情況愛好來生活就好。不勉強自己，更不對他人的選擇指指點點。

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.
