|                  |                                            |                  |

|<---------------------------------Total Sleep Time------------------------------->|


Assuming:
    T = tap tap key sound
    E = EE EEE alarm sound
    S = Sleep function to check if husband can sleep through or not

    X = Brain state during sleep begin time 
    Y = Brain state during sleep end time 


For husband H we know that: 
    Sᵪ(T) === false // can't sleep cause tap tap tap 
    Sᵧ(E) === true  // can sleep through EE EEE


Need following data: 
    Sᵪ(E) === ? 
    Sᵧ(T) === ? 


Conclusion:
    If Sᵪ(E) is false and Sᵧ(T) is true then we can say that 
    husband H's brain state X during sleep begins is not same 
    as brain state Y during sleep ends (eg: X != Y)

    And That makes H to sleep through EEE EEEE EEEEE of an 
    alarm clock but not the gentle tap tap tap of laptop keyboard

Hi! I found this gist by following this conversation thread on twitter. I'm just wondering how can you type the subscript S_y (T) in a txt file without any formatting? Thank you.

@violetguos those are Unicode characters. You have to either copy and paste them, or type them using special code. See https://m.unicode-table.com/en/blocks/phonetic-extensions/
