Heck yes, imagine having 20 year old kids in my 40s instead of 0-5 year olds! If you want to have kids don’t wait around if possible, not only will you have way more energy but all the sooner they will be able to contribute to the household and just in time for your energy to start waning, BUT there’s a much bigger benefit I never noticed before:
The biggest gain of all is the extra 10-20 years you may be giving yourself to spend with your kids and grandkids, the opportunity cost is immense, I can’t emphasize this enough.
