Step-by-step explanation:
The reason why growing older would be scary is missing your childhood wishing you can go back in time but it can also being scared of losing your loved ones and you also have to do a lot of responsibilities as an adult like do taxes, bills, taking care of your children (if you want a kid) and having to work and it's a lot of stress and some people cant do it and you know they are scared of that reason. As a kid you think it will be easy but as your growing older you will understand.
