Someone's size not merely affects the look, but also the overall quality of life. Self-esteem, depressive disorder, health risks, in addition to physical abilities are disturbed in putting on weight. It is possible to make everything right and at the same time having a gain. Should this happen, a medical problem may be the culprit. While excessive food rather than enough physical exercise are usually at fault, common medical ailments and trusted prescriptions could greatly increase size. Thanks alot : ) for your post here gywl512. One thing I’d prefer to reply to is that weight loss program fast is possible by the correct diet and exercise.

People's size not merely affects the look, but also the overall quality of life. Self-esteem, depression, health risks, along with physical capabilities are influenced in weight gain. It is possible to make everything right and still gain. Should this happen, a condition may be the root cause. While too much food rather than enough physical exercise are usually responsible, common health conditions and traditionally used prescriptions can greatly amplify size.

I see your rational and the logic of it. Seems perfectly reasonable to me! I was just tossing out that given the thousands and thousands and thousands of possible combinations, what are the statistical probablities that a virus' sequence wouldn't pop up at random by sheer chance? I s'pose that these appearances way outstrip this? Has there been any reaseach done on the origin of viruses? Do we know where they come from? Is it possible that they are end products of the degradation of the DNA of living beings? Or is my ignorance showing! I’m certainly no geneticist but I understand what you are saying.

Crazier things have been known to happen though. As for the random appearance of these DNA passages; it's unlikely that random mutation, no matter how early it began in human history, could result in the DNA of these viruses being present in a wide range of human individuals. Ancestral infection is the simpler explanation of how these viral sequences could still be found lurking in the DNA. Occam's razor is all I have to go by on this, though. One thing that comes to mind as to HOW the bornavirus RNA was translated and inserted into the host DNA: Couldn't a simultaneous infection of a host by the bornavirus and a retrovirus theoretically result in the insertion of bornavirus DNA? They're both RNA based when they enter the cell, and while the binding sites for the Reverse Transcriptase may differ from retrovirus to bornavirus, it's not inconceivable that they be similar enough to wobble together.

Still, I have always had the suspicion that viruses are the result of DNA degrading. Rather than adding themselves to our DNA, I'd like to see someone do some research on viruses being derived from our DNA... Yet again, with so many combinations of the four basic building blocks given the number of genes and such, it is only statistical that somewhere along the line these combinations for viruses and other things should crop up, huh? Might mean nothing at all... Great thought, HD…

Imagine if the immune system could refer to those genes as templates for antibodies. My guess: The genes are there for reference.
