the only hope is for it to get so bad it does permanent damage then its within the standards for treatment, but its kinda late by then.
plus my doctors doesn't believe males get hypothyroidism, which is a nother canada medical faux pas, cause men are simply not diagnosed with it.
It controls depressive moods. and after I do a lot of public stuff like the ood samples and stuff i am motionally drained and them the thyroid depression kicks in and i get so depressed i cant sleep properly
Here we go with Todd taking a stab at a science question. Todd, you know you're not allowed to dive into the deep end until you pass the swim test. Stick to chanting the mantra "Liberal Media. Liberal Media. . . ."
The actual answer has nothing to do with heat or heat transfer. The secret is navigation. Left to their own devices (free of human created light sources) bugs will use the brightest object in the sky (the Moon) as a fixed reference point and fly in a straight line keeping that fixed reference point, unless dissuaded by a stray pheromone or somesuch.
Put same bug in environment with a porch light or some other man-made light that is relatively brighter than the Moon, the bug tries to fly in a manner where the light source stays in the same location reference-wise. Easy to do with the Moon but trying to do this with a porch light at such a short distance results in the familiar death spiral or haphazard collection of fits and bursts of moths.
So, it sounds kind of weird but bugs fly into lights because they are actually trying to stay away from the light. Kind of like the success our posters have in ridding the board of trolls by complaining about them. An analogy that works on so many levels . . .

RonG got it right on the mark.
Some more info:
According to Jim Liebherr, professor of entomology at Cornell University, insects aren't actually attracted to your porch light, despite all of the little moth carcasses you may see inside the globe. Over the millenia, certain insects have learned to use the largest natural night light (which, up until about 100 years ago, was most usually the moon) to navigate. Moths will fly above the treetops, keeping the moon in a fixed location, allowing them to determine their line of movement. Unfortunately for the moth which happens to find itself in your front yard, the light sources that people create are often brighter than the moon.
The insect attempts to keep your porch light at a fixed position relative to its body, but because the light source is relatively close to the insect, the result is an ever more violent spiral leading directly to the light.
Why a moth just sits there once it lands by a light is another question you might ask. Unfortunately, the guys at Cornell don't know everything.
