    And if you’re 18, you can only date someone who is exactly 18. Can’t go any lower or any higher.

    Idk who told this to me, but what a weird contradiction. I guess it sorta makes sense.

      Nope. If your age minimum for a partner y is determined by your age x with the function:

      y = 1/2 x + 7

      then the point where y = x is at y - 7 = 1/2 x. Setting y to x leads us to x - 7 = x / 2, which happens at x = 14.

      At x = 18, y = 18/2 + 7 = 9 + 7 = 16.

      Relatedly, if we invert the function, y - 7 = 1/2 x, thus 2y - 14 = x, which gives us the theoretical maximum for a possible partner. If a possible partner is older than that, you’d be understood to call them a cougar, or whatever the male equivalent is.

        My favorite feature of the x/2+7 rule is that it implies you shouldn’t be dating below the age of 14. Run any number lower than 14 through it to see what I mean. You can’t reasonably say a 6 year old should only date people older than 10 and also younger than -2.

          Don’t you hate it when your 6 year old starts dating those people from the negative mirrorworld? No child of mine I say!

          And a newborn should be dating nobody younger than seven, while also dating nobody older than yet to be born in 14 years 😛
