Why would anyone make a lifetime commitment?
Again in the interests of teaching you to communicate more efficiently: Whenever you say "Why would anyone" when you already know that some people do this (and it's not just some bizarre hypothetical/fictional world you're discussing), this signals that it's mainly a rhetorical question and that you believe these people to be just insane/irrational/not thinking clearly.
