如果人们只能许一个现实中的愿望，他们会选择什么？
我在思考一个思想实验。<p>想象一个系统，每个人只能许一个现实中的愿望。不是金钱，也不是魔法——只是一些现实的事情，其他人如果愿意可以提供帮助。<p>这个限制是故意设定的：一生只能许一个愿望。<p>你认为这个限制会如何改变人们的愿望？哪些愿望会消失，哪些愿望会保留下来？

I’m thinking about a thought experiment.<p>Imagine a system where each person is allowed to ask for only one real-life wish.
Not money, not magic — just something realistic that other people could help with if they want to.<p>The constraint is intentional: one wish, ever.<p>How do you think this limitation would change what people ask for?
What kinds of wishes would disappear, and which ones would remain?
