I use to write a lot. I mainly wrote screenplays. I currently have forty six and making new ones and expanding pn the old everyday, however finding the time to write them down is nigh impossible:marriage, kids, and business dealing.
I love to read. Again I haven't found the time for a book lately (I have gotta drive my lazy ass the hour drive to get Pygmy by Chuck Palahniuk), but nothing is more engrossing and stimulating than a good book.
Quantum Physics, yep I said it. No I do not understand the math nor did I reach any level in high school nor university to even suggest I have the foggiest (I'm good with money, but past geometry it gets a bit reaching). Anyway I love the concepts.
