Walking Through Paper

You have a regular sized piece of paper. How could you cut a hole in it large enough for you to walk through?

Fold the paper in half and make cuts that are almost entirely across the width of the paper. Switch between sides. When the paper is opened there will be a very large hole that you can climb through (carefully).

I Make Memories That Last a Lifetime

I make memories that last a lifetime,
Without me you’ll be miserable,
If you miss me you can gourge and it’s okay.
Some say I am naturally split in two.

What am I?

Sleep. It’s the time your mind organizes memories and knowledge. Sleep deprivation is miserable (as you well know if you’ve experienced it). If you miss a few nights of sleep, you can sleep more to catch up with no problems. And some believe that segmented sleep, where you sleep, wake for an hour, then go back to sleep, was the dominant form of sleep before the Industrial Revolution.

Ages Of Myself and My Brother

My current age, is the age of my 14 year-old brother plus one third of my age. How old will I be when my brother is twice his current age?

I will be 35. I am currently 21.

x = my current age

x = 14 + x/3
3x = 42 + x
2x = 42
x = 21 (so 14 years later, I'll be 35)
