In the treetops

Yuko's nephew asked her to take him to Forest Adventure in Itoshima, which is an outdoor activity centre where you move through the forest canopy by tight rope walking and zip wire riding..
Activities are held at heights in excess of 10 metres so safety harnesses are always used.

New adventurers start at 30-minute intervals.

How would you feel doing this?

A quick poll of students present in one class showed that given the choice of an activity above ground or underwater; 'above ground' would be the overwhelming preference.

Would you feel acrophobic or claustrophobic?
