What are the limits(極限) of human body? The BBC’s Focus magazine has some answers.
How cold can you stand?
Normal body temperature is around 37℃. At 35℃ you’re unable to write your name. Even walking is very difficult. At 33℃ you may find it difficult to think, understand and form(形成) opinions properly. By the time you have cooled to 20℃, your heart would have stopped beating.
Limit: 0℃. Ice would form in your tissues(纖維組織), killing all the cells.
How spicy can you eat?
There is capsaicin(辣椒素) in many foods. The more capsaicin, the hotter the dishes are. If you’re healthy enough, you can survive(存活) eating a teaspoon of pure capsaicin. But you would find it impossible to eat anything else for a few hours.
Limit: 5g capsaicin.
How fast can you run?
The fastest man in the world is Asafa Powell. The runner finished the 100m in 9. 74 seconds in 2007. This gives an average(平均的) speed of 36. 96km/h.
Top runners are at their fastest around 80 metres, so a runner’s greatest speed may reach 43.06km/h.
Limit: 43.06km/h.
How loud is too loud?
The loudest sound you can hear is 168 dB(分貝). Sound louder than that may do harm to your ears. The loudest sound ever recorded was the eruption of Krakatoa(卡拉卡托火山爆發) in 1883. It was 180 dB, 160km away.
Limit: 168 dB
