Some people are pretty good at acting their age.
They like to be cautious and sit around doing nothing.

After all, it's good to play it safe.

To keep things low-key.

And very serious.

Because you are a grown-up. Right?

And it is important not to take risks. Because if you do, you might...

join your children and brother in a game of
Run-Down-The-Hill-As-Fast-As-You-Can-No-Slowing-Down-Or-You're-A-Wimp and end up like this.

Then you will get lots of time to sit on the couch and re-evaluate your actions and think about...
how you can't wait to stop acting your age again.
