1. The Strange Role of Track Judges in the 1964 Tokyo Olympics
- This is about the 1964 Tokyo Olympics.
- In the above picture the standing people in white dress were the technical members.
- These people were standing in front of where the race was taking place.
- They were standing near the ending point of the race.
- These officials were called Track Judges.
- They had an important job:
- To see which athlete finished first or cross the finish line
- In 1964, there were no high-speed cameras at races.
- Without cameras, it was hard to tell who won close races.
- How Track Judges worked:
- They stood at different angles near the finish line
- They watched for the first foot to cross
- This method might seem strange today.
- But it was very important for fairness in the Olympics.
- This shows how Olympic history has changed.
- It highlights how technology has improved sports:
- Now we use cameras for finish line accuracy

3. The Real Addiction

- Gambling is actually the most common addiction.
- Research on gambling addiction has taught us a lot about the brain.
- Surprising fact about gamblers:
- They often don't play just to win money
- They play to escape their real life
- Gambling can cause a dissociative experience:
- The gambler's mind becomes calm

4. Rare Diseases That Erase Fingerprints
- Fingerprints are often used to identify people.
- Some people are born without fingerprints:
- This rare condition is called Adermatoglyphia
- Some people lose their fingerprints later in life due to diseases:
- Epidermolysis bullosa is one such disease
- Psoriasis is another
- These diseases can make fingerprint lines fade or disappear.
- Having no fingerprints is very rare.
- This creates problems for fingerprint biometrics:
- Fingerprint-based ID systems may not work for these people
- These conditions challenge how we use fingerprints for identification.
- Adermatoglyphia is sometimes called "immigration delay disease":
- Because it can cause issues at border controls
- Fingerprint loss can happen gradually in some cases.
- These are examples of rare diseases affecting identification.
5. Memory Loss Explained
- Imagine someone has an accident and loses all memory.
- They might wake up and ask, "Who am I?"
- But how they still remember?:
- Speak
- Use grammar
- Know words
- This is because we have two types of memory:
- Episodic memory
- Procedural memory
- Episodic memory:
- Stores every life events which happened with you or your life
- Episodic memory Can be lost in accidents
- Procedural memory:
- Stores skills like language (what we have been speaking/talking since childhood)
- Usually stays even if episodic memory is lost
- These two types of memory are stored in different parts of the brain.
- Losing episodic memory doesn't usually affect procedural memory.
- Only severe brain injury affects both types or Procedural memory:
- This happens in just 0.01% of cases
- This explains why people with amnesia can still speak.
- It shows how complex brain function is.
- This fact is important for understanding memory loss.
