# Advantages of using methods instead of free functions:
# 1. Easier documentation - all related behaviors are attached to the class.
# 2. Encapsulation - data and logic are kept together in one place.
# 3. Easier maintenance - when class details change, methods can be updated easily.
# 4. Clearer code - you can write person.is_adult() instead of is_adult(person).
