Your a small person. I have a friend who weighs in at 140(now) to, and he's 5'9" or 5'10, skinny looking, but not at all WAY to skinny looking.
Perhaps your poor eating was the reason behind your 130 weight, he was also 130 for a long time and ate like complete sh*t. He moved into my place a while back and since almost all I eat is health foods he was eating what I was eating, he gained 10 pounds in just over a month. His skin cleared up as well and honestly he just looks 10 times better than he ever has.
