Second, if you continue working after you claim Social Security benefits at less than full retirement age, those benefits would be reduced if you earn over a certain amount. Until you reach full retirement age, Social Security would reduce your benefits by $1 for every $2 you earned over a set yearly limit. (In 2009, the limit is $14,160.) This limit applies only to income you earn from current work, not from any pensions, investments, or other sources of income not derived from work you are doing at the time.

Skin tags and moles are both skin growths, but skin tags are always benign and moles sometimes precede the development of melanoma. Generally, these growths are not treated unless there is a pressing reason to do so, such as aesthetic concerns or worries that a growth has become cancerous. Perhaps the key visible difference is that skin tags tend to protrude, while moles are flatter, with a raised surface area. In the case of skin tags, the growth consists of a benign tumor, usually close to the patient's natural skin color, developing in the form of a flap.
