I agree with Mark Twain when he said: Age is an issue of mind over matter. If you don't mind, it doesn't matter. I have been writing for most of my life, but did not tackle a novel until I had retired. For the longest time I sat around planning a future in retirement, but it felt shallow compared to sitting at my computer writing. My counter arguments were age, time, health, or why? Mark Twain set me straight. Creativity is not bound by age or geographical constraints. It doesn't matter. Just write!
