My hubby's 37 so 40 doesn't seem that old to me. 16 years between us (i was a December baby)
At the moment all the planning and organising is very consuming, gives me something to focus on outside of work tho which is nice. I'm a little bit OCD and ADHD so I will focus on one thing until its planned to the last detail and underway then start the next occasionally editing the original plans as well. I like to be informed about the future.
