Cat scratch disease (CSD) is a bacterial disease caused by Bartonella henselae. Most people with CSD have been bitten or scratched by a cat and developed a mild infection at the point of injury. Lymph nodes, especially those around the head, neck, and upper limbs, become swollen.
Your Social Security benefits are calculated based on your highest 35 years of earnings or half of your spouseâs benefits -- whichever is higher -- if you retire at full retirement age (currently 66). For a worker retiring at age 66 in 2012, the maximum benefit is currently $2,513 per month. If both you and your spouse earned the maximum amount that counts every year ($110,100 in 2012, but just $16,500 in 1977), you could each receive the maximum monthly benefits.
The maximum Social Security retirement benefit will be $2,663 per month in 2015, though few people are able to collect this amount. Along with this benefit increase, many important figures having to do with Social Security and SSI eligibility, taxes, and benefits have changed.
