You can't use Console.Read() to get a number, it only reads one character, use Console.ReadLine() wrapped in a TryParse accordingly with the numeric type to be used;

int age = 0;
int.TryParse(Console.ReadLine(), out age);

You can then check if age == 0, which indicated the input was not a valid number.
