Okay kiddo, you know how we all have genes that determine things like our hair and eye color? Well, those genes can sometimes be turned on or off based on different things that happen in our bodies or in the world around us.
Now imagine those genes are like a valley with hills on both sides. If the genes are turned on, it's like walking up one of the hills and getting to the top. If they're turned off, it's like going down into the valley.
Sometimes, when certain genes are turned off or on, it can impact how our bodies work. This is called an "epigenetic valley" because it's like the genes are stuck in a certain state or position.
Researchers are studying these valleys to try and figure out how they impact things like cancer and autoimmune diseases. It's a really complicated topic, but basically it's all about how our genes can change based on different factors in our lives.
