Of course you can substitute for the word “travel” any number of things you enjoy:

Last week the question arose as to what we would do differently if we were immortal… I answered that I would travel more.

Later the question was asked, what would you do differently if you found out you had only a short time to live. I answered again that I would travel more. Click, buzz, whirr…does not compute, does not compute… Given that I would travel more if I was to live either less or more the probability that I was at just that level of mortality that I should not be traveling now must be vanishingly small.
