Like we mentioned before some of your Tasks are just quick reminder and just need a name, but don't need a message.
In this case let's look at some things you might do with a message.
For Dr. appointment a message each time would give you a record of appointments to help you sort out when to go again. Just move this Task to the Medical folder and revive it when the next checkup is due.
Looking at the previous message below we added some info you might want handy and we also popped in a comment so you can see what that looks like.
