Well, good at living a long time, at least. Nature reports on a study that finds about 55 percent of the factors that grant a long life come from your inherited DNA:
The findings should aid in the quest to find specific genes involved in ageing and to develop treatments for ageing and age-related diseases, says study co-author Ben Shenhar, a biophysicist at the Weizmann Institute of Science in Rehovot, Israel.

To tease out these factors, the researchers re-examined data, going back to the 1800s, from twin studies in Denmark and Sweden, as well as studies on siblings of centenarians in the United States. Such studies can identify genetic components of traits, Shenhar says, because identical twins share 100% of their DNA, whereas fraternal twins and other sibling pairs share about half on average.
