ELI5: Explain Like I'm 5

Aging brain

As we get older, some of the cells in our brain (the organ in our head that helps us think, remember, and learn) can start to break down. This means the signals or messages that our brains usually send to our bodies can be delayed or not work as fast as they used to. It's like the connection between our brain and body isn't as strong. This can make it harder to remember new information, learn new skills, or problem solve. The good news is we can help keep our brain healthy as we get older by eating healthy and exercising, taking time to relax and getting enough sleep.
