Sensitivity to caffeine varies for individuals, but in healthy adults the half life for caffeine is approx 6hrs meaning your body eliminates half the caffeine you have drunk in 6 hrs. Ref: Caffeine Pharmacology

Caffeine interferes with sleep. One study found that consuming caffeine 6 hours before bedtime reduced total sleep time by 1 hour.

4. The Harry Potter Algorithm

November 25, 2015

Here is the Harry Potter Text:

Harry Potter and the Sorcerer’s Stone, J.K. Rowling

“Have you ever seen anything quite as pathetic?” said Malfoy. “And he’s supposed to be our teacher!”

Harry and Ron both made furious moves toward Malfoy, but Hermione got there first – SMACK!

She had slapped Malfoy across the face with all the strength she could muster. Malfoy staggered. Harry, Ron, Crabbe, and Goyle stood flabbergasted as Hermione raised her hand again.

“Don’t you dare call Hagrid pathetic you foul—you evil—”

“Hermione!” said Ron weakly and he tried to grab her hand as she swung it back.

“Get off Ron!”

Hermione pulled out her wand. Malfoy stepped backward. Crabbe and Goyle looked at him for instructions, thoroughly bewildered.

“C’mon,” Malfoy muttered, and in a moment, all three of them had disappeared into the passageway to the dungeons.

Hermione!” Ron said again, sounding both stunned and impressed.”
