Hey, 40's is not even considered the prime of life. You are still a very young person and should just enjoy life as it unfolds for you. Most times you meet someone who becomes important in your life purely by accident or coincidence and not when you are looking for them. I am in my 60's and married but I often meet people and have learned to trust others which is a important aspect in making acquaiintences, neighbors and friends. And as a medical person I know about aging and you are a young person.
