When I was a kid I wanted to be an astronaut... now that I'm older and wiser and realise how complex going into space is and the effects it can have on your body (especially long periods in space), I'm not so keen. A short flight into space like an aeroplane flight where you can see earth below you maybe... if that ever becomes a commercial prospect (not that I could afford it!), but nothing more adventurous than that. Definitely not colonising Mars or anything that means you can't come home!
