Or were all the old second counting systems wrong?
Many people have pointed out that if you start a timer on your phone and count out to 45 Mississippis, hippopotamus or number-one thousands it now ties out to a minute.
I have tried it a dozen times myself and after 45 counts I get anywhere between 54 to a minute and 4 seconds.
I specifically remember counting chunks of time as long as 15 minutes and not being off by a minute.
Once you hit a certain age, every week goes by faster than the previous one.
I think that happens at every age. Every new day is a smaller fraction of your life then the previous day.
