I fondly remember the first time I went on the Tower of Terror ride at Disney, holding on for dear life and screaming at every floor. I wondered recently how many times I would have to go on the ride, before eventually the terror would pass? In my personal life I have felt terror a few times; losing my son on a busy beach in Florida was the worst, and a more common one later in life is that realisation you have lost your mobile phone. I hate that feeling of panic and indecision, of being helpless and not knowing what to do. I’m sure that the feeling of terror wouldn’t pass no matter how many times you lost your phone – instead we change our behaviour and organise ourselves so that it will never happen again.
