These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls.
If you will reach full retirement age in 2015, you may earn up to $3,490 per month without losing any of your benefits. But for every $3 you earn over that amount in any month, you will lose $1 in Social Security benefits.
Social Security earnings limit is $15,720 for 2016, if you are working and collecting your Social Security payments. If you earn over $15,720, you lose $1 for every $2 you earn, after you hit the maximum. That sounds bad and you do lose half of the SS payment over the earnings limit BUT you still get full Social Security for the first $15,480.
