If that is true (and appearing in LOL is no proof of that) then it is ridiculous. As Jacqui says, the age of tourists - not just the older ones, young kids have died recently too - needs to be strictly controlled. To ban it denies a huge number of people the chance to experience it. I do get the impression though that this is being sold perhaps as a scary but safe experience, similar to a rollercoaster ride, whereas in reality it could be a high risk excursion where lives are on the line. There needs to be a competent risk assesment - if it is scary but safe then great, if it is a risk to human life then it has to go.
