I have occasionally heard a rule of thumb about age differences in relationships: that a man shouldn’t date a woman who isn’t at least seven years older than half his age. I just mentioned this “rule” to a friend who had never heard it, and she wondered where it came from. I have heard it more than once (and vaguely remember some source, not necessarily a credible one as I recall, attributing it to Gandhi), but I don’t really know where it came from. Does anyone here know?
I also thought that I saw a thread on this topic about a year ago, but couldn’t find it when I searched.
