What is the secret to this?

What is the secret to this?

A1
C1
E3
H3

What comes next?

I2.

Each entry is a letter, in alphabetical order starting with A, followed by the number of occurrences of that letter in the phrase “What is the secret to this”.

There’s one ‘a’, thus we get A1. There are no ‘b’s so it doesn’t appear, then there’s one ‘c’, and so on.

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.

Celebrate, Hide Their Shame or Commit Crime

Some use me to celebrate,
Others use me to hide their shame,
Others use me to commit crime.

What am I?

Alcohol. People have a drink to celebrate, but also drink to hide their shame. Lastly, drunk driving is a crime.

A mask is also a valid answer. They can be used to celebrate Halloween or at dress-up parties, a mask can hide your shame and masks are used by thieves.

Update: This one has more valid answers than I thought. Money, drugs and night also work.

A U2 Concert

U2 has a concert that starts in 17 minutes and they must all cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight. A maximum of two people can cross at one time. Any party who crosses, either 1 or 2 people, must have the flashlight with them.

The flashlight must be walked back and forth. It cannot be thrown and other tricks like that are not needed to solve the problem. The solution is simply a matter of allocating resources in a certain order. Each band member walks at a different speed. A pair must walk together at the rate of the slower man’s pace:

Bono: 1 minute to cross
Edge: 2 minutes to cross
Adam: 5 minutes to cross
Larry: 10 minutes to cross

For example: if Bono and Larry walk across first, 10 minutes have elapsed when they get to the other side of the bridge. If Larry then returns with the flashlight, a total of 20 minutes have passed and you have failed the mission.

This is one of my favorite brain teasers and I want to give you the satisfaction of figuring it out on your own. If you’re having a hard time, here’s a hint: There is a valid answer that doesn’t require tricks like throwing the flashlight or shining it backwards or having some other means of moving the flashlight.

There’s an assumption people often make that keeps them from solving this. Two members cross the bridge each time, but neither one of the two who crossed necessarily need to return. Think about how that would be possible. If you’re still stuck, use objects to simulate their movements. Use whatever you have laying around – pens, paper, erasers – and move them back and forth. Good luck!

The Thinner It Grows

You use me from your head to your toes.
The more you use the thinner it grows.
For years I was not often used,
Not using me now is not excused.

Soap.
