Age and SBD's
Silent But Deadly Farts have been around since I was young. However, I have always been aware of the fact that older people are more likely than not to be the cause. Previously, I thought that perhaps it's experience, or maybe bashfulness, but now I realize that it is probably physiological! As we age, our skin tends to wrinkle everywhere. This is not disputed. Why should the anus be any different? An age wrinkled anus would, of course, have more ridges along it's walls than a young anus, thereby limiting their effectiveness at containing gas. This can also explain why some people just don't fart often. Any one unable to fart should consider using anti-wrinkle creams on their anus to try to improve containment.
