I pretty much know myself well enough to be certain that I am not going to do any hectic motor biking or the like. But what I did think would be fun is to try out quad biking before I turn 40. It ended up that none of us have been quad biking before and for the ultimate ride, we all got to try it out for the first time on the sandy banks of a Kenyan river. It was great fun and if the opportunity would arise again I would definitely do it!
