What I did to be safe from terrorism.

I made a combination by putting my hand up and it only unlocks if I do it and it was to stop terrorism and I don't believe anyone has made a combination to do it that way because you would have to make a combination with numbers at first and then it goes to doing it yourself like putting your hand up and making a combination where only you can unlock it and it is the best one there is because there is a small chance someone can figure out your combination and no one can debunk it out as not being right. I made it 30 min ago. I am 27 yrs old.
