Question: why does time seem to go slower some days than others? some days i dont remember the day because its gone so quickly or i dont realise the time because its been so quick, but some days the day goes really slowly and it feels like ages until the end of the day or before i can go to sleep?

  HI @nhanlon12
  
  I don’t know of a reason for this. I guess it’s to do with concentration, when you’re focusing on something and enjoying it you don’t notice time passing, but when there’s nothing to occupy your brain you’re more aware of time passing.
  
  I also think that when you’re a child your concept of time is really different. I remember when I was little a year seemed like FOREVER, but now I’m an adult they seem to pass worryingly quickly. But maybe this is just the way memory works?
  
  Sorry there’s no science in this answer at all! Anyone else know an actual reason why this might be?
