Siobhan (11) asks “Do fish sleep?”

Siobhan. You maybe interested in why all animals (ourselves included) sleep. It is in sleep that we make our memories. Our nervous system and brain work because of fantastic cells called neurons. When we feel something, it is the neurons in the nerve system of our hands that send messages to the brain about what we are feeling. When we sleep it is the neurons in our brain that link up and create the memory of that touching experience.

Thanks for the question. If you have any further questions you can make a comment or ask another question.
