I get this question a lot, since people think I should settle down in my age (I am 33). I am not sure how to respond to this.

My main reason is that I don't think a relationships suits my lifestyle, but obviously that is not what I tell them.

My regular response is something like "Why? Are you interested?" or "I don't have time to view all the applications".

Any suggestions that doesn't sound "too try hard"?
