What is epigenetics? - Carlos Guerrero-Bosagna?

Imagine your body has a special notebook where it writes down instructions for growing and changing, that’s what epigenetics is like!

Your body uses this notebook to remember things, like how much you play or how much you eat. These memories help decide if you’ll be tall, short, or even how well you’ll do in school later on.

Like a Coloring Book

Think of your genes as the lines in a coloring book, they show what can be colored, but not exactly how it will look. Epigenetics is like the crayons and colors you choose, it changes how the picture looks without changing the lines themselves.

When you eat too much candy or don’t sleep enough, your body adds notes in this special notebook. These notes tell other parts of your body what to do, maybe making you grow faster or slower than usual.

Sometimes these notes can even be passed down to your kids, like a little gift from your lifestyle choices!

So epigenetics is like a clever way for your body to remember and share stories about how it lives. It helps shape who you are, without changing the original story inside your genes.
