It seems like lately, time has been flying by, and I never have enough to get anything done really. Is it just me?
No, it is not "just you". Sadly, your perception of elapsed time continually changes as you get older.
On average, at least as a close approximation, it appears that most people perceive the duration of any given time interval in accordance with the fraction it forms compared to their age.
This means that each of the following will seem to form a similar amount of our perceived time: one year between age one and two; two years between age two and four; four years between age four and eight; etc..
Compare how long a time appeared to elapse between your sixth and seventh birthdays - it probably seemed to "last" about twice as long as the year between your twelfth and thirteenth birthdays.
This perception of time is not absolutely set in stone.
Most people find that time seems to drag along slowly if they are bored, miserable, suffering, or experiencing something very new which is particularly unfamiliar (e.g. first day at a new school);
But by comparison the time seems to flash past if you are comfortably enjoying yourself in familiar surroundings (e.g. having fun with your best friend).
when we get late we feel like this.
