92nd Birthday

My sister-in-law turned 92 on Saturday. She looks pretty good for her age. There is a lot of longevity in my husband's family. He has a 79 year old sister, this sister who is 92 now, and another sister who is going to be 94 next month, and one brother who is 79.
There were 12 children in the family to begin with. Now it is down to 4. It looks like the sisters are going to outlive the brothers. Their mother was 90 when she died.
