I estimate that there is a 1 in 10 million chance that Forge will go postal and successfully kill me.
Which is actually more dangerous than terrorism- where there is probably a 1 in 20 million chance that I will be killed by a random terrorist.
Of course it might be wise to consider:
A 1 in 3 chance that I will die of cancer
A 1 in 100 chance that I will die because I am a bad driver.
A 1 in 25 chance that I will loose my job because I waste too much time on slowtwitch.
