Josh Groban

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.

When I was 23, I went backpacking around Australia for three months. I saved up a few grand, quit my job and flew to Sydney, then went to Melbourne and up the East Coast, which was an incredible experience. I remember running out of money and getting my mum to send me a few hundred quid, which helped me get by.

Personally, I like to juice up several different kinds of fruit and vegetables - which may include various combinations of bananas, red bell peppers, apples, carrots, celery, broccoli, spinach, parsley, tomatoes, cucumbers, etc.
