My theory on time, and how it effects my life

I’ve been experiencing a strange sensation over the last 15 years or so that time is speeding up. I have a notion that plenty of people are feeling this effect as they get on in life, and much of what I am saying probably feels cliche and old hat, but the idea never really held much sway in my mind until the last few years.
Time is speeding up. For me, anyway. How do I know this? Unfortunately, I don’t have a good way to quantify this phenomenon in any sort of scientific way, and to someone watching casually from their teens or early 20′s, this sounds like bollocks, if I might borrow a term from our British friends.
I know that time is speeding up for me because I have way less of it than I used to, but more importantly than that, my perception of time is nothing like it was when I was younger.
As a kid, an hour seemed like three. Now, an hour seems like 15 minutes. Week long vacations seemed to last for months. Now they feel like a day and a half.
As a teenager, 2 years sounded like a lifetime. Now it sounds like not enough time.
I provided this simple chart (shown above) to sort of help explain my notion of time. The large labeled lines represent major points on my life, and all the little red ones represent various sub-events. As you can, later in the chart, these sub-events start to go up in volume. I think those are the key.
Would love your feedback as to whether or not I am feeling this way on my own, or if others share my plight.
