I've noticed I am getting older. My hair is getting grayer, my purpose is more focused, I rarely get bored as I am always busy, I have some wrinkles in my skin, and my marathon times aren't as good as they used to be.
I also am wiser, and happy. Things are great, but I am not a huge fan of blinking my eyes on Monday and it is already Friday. Time feels like its moving by much quicker the older I get.
