It may be said that there are three kinds of heroes: famous heroes, fictional heroes and personal heroes.
A famous hero is someone that a lot of people
know such as a sports person, a musical artist
or a (political) leader.
A fictional hero is someone from a movie, a cartoon
or a fictional place, such as Thor, Batman or Harry Potter
A personal hero is someone that you personally
know, such as a friend, a family member,
a trainer or a teacher.
