Sanh Trong Tran turns 105-years old on Monday.
The father of nine was surrounded by his children, grandchildren and great-grandchildren.
He fled Vietnam in 1975 and settled in Wyndmoor.
Tran was employed for years at Chestnut Hill Hospital.
We asked him his secret to living a long life and he told us -- it's in his genes. He's had six other relatives who lived to 105.
