Thanks for your reply at first.

We are operating a travel site. Most of our clients are wealthy and senior people. Considering visual problem of some senior people, what is the best font size we shall adopt. My boss is complaining our current font size, which seems to be nuisance for him due to his astigmatism. ;)

That might give you some ideas.
