Several of my friends still feel very angry and bitter about it and just won't accept it. In consequence they tell me I shouldn't accept it. I get all these stories about these heroic people who have organ after organ removed and say, I'm not going to die; I'm going to live; and they go on, year after year. It makes me feel I'm being terribly feeble. I feel rather guilty, as if what they're saying is, well, you're not trying hard enough.

I can't really see what else I could be doing. I'm very confused about all this. I don't quite understand what I ought to do. Well, I suppose one could be a Chichester and rush across the Atlantic in a boat. But you know, really, I'm too tired for that. I think what I want to say to people is that if you're in this situation it isn't nearly as bad as people who try and put themselves in your position think it is.

请问：句中 I suppose one could be a Chichester and rush across the Atlantic in a boat 中的 one指代什么？
