Whut it is, is them thar boy molecules want to get all jiggy with the girl molecules REAL BAD, and never let go. If'n they's too cold, not much happens, even if they is an equal number of them all mixed up close together. But if y'all lets thesehere boys and girls get too hot, its like the clothes all get flung off and they start to seriously party down. Cooling them off don't help much then- its too dang late, Bubba. Hope this helps.... The ol' Doc.
