Consider the following Python code: 
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def celebrate_birthday(self):
        self.age += 1
If you create an instance of the `Person` class called john with age 30 and then call john.celebrate_birthday(), what will be the updated age?

31
29
