I think it is a wonderful idea if you have found the right person. My grandmother was 40 when my grandfather passed away. She is 79 now. Back then, she was (and still is) beautiful! She had several people call and ask her out back then but she would not go. I never understood it and neither did her two daughters for that matter. In my opinion, she should have dated and if it eventually led to marriage then thats awesome. Everyone deserves to grow old with someone they love. She was so young and pretty. It would have been great for her to share the rest of her life with someone she loved and loved her back.
