It is known that an adult's birthday is March 10, and his age this year is exactly the sum of the digits of his birth year, so how old is this person this year? (Our country's civil law stipulates that the age of adults must be 18 years old)
已知一名成年人的生日是3月10日，他今年的年龄恰好是他出生年份数的各位数字之和，那么这个人今年多少岁？(我国民法规定成年人的年龄要满18周岁)
