Answer:
I would probably fear not being remembered or how my family would do without me.
Explanation:
This is because if you missed something in your youth make sure you do it now or help someone else to do it. If you fear getting older then just remember that you will always have people to care for you old or young and you lived your best life. If not then have a little fun so you are satisfied with your life. :)
As for handling not being remembered just do something noteworthy or if not just be kind and remember your family will always remember and love you.
Your family would get on fine without you. If you are worried then help them to get a good job and income so that they will manage without you. But remember, HAVE FUN!!!!
