  • Introduction to Age Detection Game(0'000'32)
    Brain Games is at the beach to explore how brains handle different life stages including tweens, teens, adulthood, parenthood, and golden years.
    Players must raise their hand when they hear a tone to determine what stage of life their brain is at.
    A colored wheel contains different audio frequencies measured in hertz, and participants indicate when they hear tones at specific frequencies.
    The game reveals the participant's age based on their ability to hear different frequencies.
  • First Frequency Test - 8000 Hz(0'320'46)
    The first spin lands on 8,000 Hz.
    Almost everyone raised their hands indicating they heard the tone.
    This frequency is audible across all age groups being tested.
    The wheel is spun again to test a higher frequency.
  • Second Frequency Test - 12000 Hz(0'461'04)
    The second spin lands on 12,000 Hz.
    If participants raised their hand, the hosts guess they are under 50 years old.
    The prediction was correct.
    This frequency shows age-related differences in hearing ability.
  • Third Frequency Test - 19000 Hz(1'041'19)
    The third spin lands on 19,000 Hz.
    If participants raised their hand, the hosts guess they are younger than 20 years old.
    The hosts successfully guessed all participants' ages based on their hearing responses.
    Younger people could hear the highest frequency while older participants could not.
  • Scientific Explanation(1'191'38)
    The human range of hearing is typically 20 to 20,000 Hertz.
    The ability to hear higher frequencies predictably decreases as people age.
    Younger people perform better at hearing high-frequency sounds.
    This physiological difference in hearing ability allowed the hosts to accurately determine participants' ages through the frequency test.
