People have very different opinions about this, lots of people think that it just disappears because it was just a part of your body and brain working so when you die it no longer exists. Lots of other people think that it carries on in some form, people believe all sorts of different things. I think that we don’t have any good evidence about what happens to it so people should all make up their own minds about what they think happens.
I don’t really know for certain, as there isn’t any way that we can test it to find out. I personally think it just fades away until you are only a memory in your friends and family. Some people think it gets passed on to another life. Other people think it goes to heaven. There isn’t really an answer to this question, so you’ll have to decide for yourself what you think.
