The battle to find a workplace that's wheelchair accessible is a feat in itself, let alone an employer who's going to be cool about employing someone with a disability in a job you actually want to do.

In my own home, where I've been able to create an environment that works for me, I'm hardly disabled at all. I still have an impairment, and there are obviously some very restrictive things about that, but the impact of disability is less.

In Australia, a deaf person attending an interview must take their own interpreter at their own expense, or ask the employer to provide one. Believe me, nothing says 'I'm the best person for this job' quite like asking an employer to pay to interview you.

People with disabilities are simply part of diverse communities in the U.S.

We don't have real control over death. You could die of a heart attack, a building could fall on you, you could be in an accident, you could have a fatal disease. So, how should you conduct your life? You just go ahead and live, taking reasonable precautions - like handling the mail more carefully.

If you really want to know what motivated me as a young man, it was a fear of death.

The more we learn, the more we will be confronted with decisions that we've never had to make before about life, about death, about parenting.

A lot of people fear death because they think that so overwhelming an experience has to be painful, but I've seen quite a few deaths, and, with one exception, I've never known anyone to undergo anything like agony. That's amazing when you think about it. I mean, how complicated the mechanism is that's being taken apart.
