There are many types of intelligence. Emotional intelligence, empathy, street smart, book learned, to name a few.
So, to continue the analogy, In each person there are many bulbs, some brighter than others, some steady, some flickering randomly. I.Q. Is one such bulb, but certainly not the only one.
Also to be considered are the hundreds of hues in the light, and the many levels of saturation each hue can take.
Finally there is the focus of each bulb. Some of them focus their energy with laser precision, and others spew it in all directions, and it is diminished through the unshakable inverse square law.
All of this leads to one enlightened truth.
Go with the biggest tits.
The thread seems to have shifted to how important brightness is in a partner. Someone you have dinner with, go to movies with, and cook breakfast for in the morning. Funny, but I don't see many reviews describing such things.
