Collect at 62 and still work full time

I would suggest you delay applying for survivor benefits for two reasons : The "earnings limit" and higher monthly benefits.

First, if you work while getting Social Security survivors benefits and are younger than full retirement age (age 66 for you), your benefits may be reduced if your earnings exceed certain limits. To find out what the earnings limits are this year and how earnings above those limits reduce your Social Security benefits, ask for How Work Affects Your Benefits (Publication No. 05-10069).

Second, each month you delay the start of survivor benefits, your monthly check will grow by about 0.4 percent.
