There is a bridge has 2 meter width,if put it on the flat road,you will not feel any wrong to across it,but if put it between on the middle of two heigh mountains, I think more and more people will feel horrible to across it.
so base on the above state,the stuff is not changed,but the evironment is changed,so our minds are changed,look at into the handicap and odds that does not make you changing your mind,just change the environment.
whatever people is brave, if let him to across the bridge which on the middle of the mountains,he will be fear。you should find the reason for what your choices,to find all of the details to prove what your choices.
