It is unlikely to occur, but being a curious person I believe in trying everything in life at least once. How else would I know if I like it? - my opinion would be based purely on prejudice. As a consequence I take every opportunity to try something new to find out if I like it – some things have turned into hobbies (e.g. diving and snorkelling and trekking); other things I only do when it is very interesting (e.g. rafting at grade 5 or 6 rapids) and a few times it has ended up in one-time tries (e.g. skydiving, paragliding and ice climbing on a glacier) – not because I don’t want to do it again but because they are offered few interesting places and are often quite expensive.
