Arbitrary Appropriate Dating Age
twitch sigil
According to Leo the Road Rage Dog over at Forum 3000, the logarithm base 2 of the ages of two people dating should be within .5 of each other.

I've long since held the opinion that the maximum appropriate age difference between two people dating isn't a simple fixed value like 5 or 10 years. It intuitively seems to me that the appropriate maximum age difference should scale up with an increase in the age of the people in question. I once expressed this as a percentage of the age of the oldest, but the logarithmic equation described above expresses this idea much more precisely. And if you don't like the results, you can simply tweak the constant of .5 higher or lower.

My appropriate dating age range.

Whew, I'm safe on all fronts. Now isn't that a relief! ;-)

Houston, we have a problem ....

Even if I wait for your next birthday, there's still a problem. Well, shit! We'll just have to ignore it then! :)

i've heard an equation for reasonable ages
assuming you are the older person, your date should be at least half your age plus seven.

Right, now I've embarked on a mission to graph and compare these different equations, which has lead me off on various tangents (anyone know if there's a log2() C++ function in some easy-to-get library?); I'll let you know what I come up with. :-)

You're looking for something like:
[Error: Irreparable invalid markup ('<math.h>') in entry. Owner must fix manually. Raw contents below.]

You're looking for something like:
#include <math.h>

float log2(float in)
return ln(in)/ln(2);

Thankee. I was wondering whether digging out my old math texts or tracking down a library and apt-getting it would be easier.

Fortunately, it seems that simply being mathematically goldfish-brained and advertising it is all I need to do. ;-)
