Being a teen is a bit of a rollercoaster ride – there's fun and excitement and new discoveries, but also sometimes pain and heartache and acne.

This is the time in your life when you will most likely experience the greatest amount of change – you will grow from a skinny, squeaky voiced grade eight boy to a strapping matric with a deep voice in just five years.

This is a tall order for anyone. Health24 takes you on a shortcut about what to expect – even before it happens.
