The Top 100 Reasons Not to Have Kids (and Remain Childfree)
1. You will be happier and less likely to suffer from depression.
2. (Assuming you get married), you will have a happier marriage.
3. You will have the capacity and time for meaningful, engaged, quality adult relationships.
4. You will be able to save for a comfortable retirement.
5. You are more likely to be an engaged and involved aunt or uncle because you are not jaded and worn down by your own kids.
