Life speeding by...

So this week I went to the dental hygienist. She asked if I had any idea how long it had been since my last visit. Now I knew I'd been on the lam for a while; ignoring appointment cards and phone messages, pretending to be out of the country. But I thought a year, maybe 18 months tops.
Alas no, it turns out 2011 was the last time my teeth had been scraped and polished. 'This may be uncomfortable,' the hygienist warned. All I can say is that her interpretation of the word is quite different to mine. As I lay there, y'know in agony, my mind turned to how fast life seems to be speeding by. And I wondered, is there any way to slow it down?
Actually I can't understand why it's happening. I had thought it was because I've written and published five novels in five years whilst also keeping up a career as a freelance journalist. Sheer routine and hard work has each day slipping seamlessly into the next. I decided to give myself longer to work on my current book. But that hasn't slowed the breakneck speed time seems to be flashing by. If anything the opposite is true. I feel like I'm sprinting just to keep up with myself.
Perhaps people who have lives with constant change, with new people and new places, don't feel this way. Maybe its the sameness of my everyday that's to blame. But since that's not likely to change any time soon there's no way to find out.
So is it possible to slow down time; to make days and weeks last longer? Or is this only get worse?
I'd really love to know!
