What do you think gets better with age?

As per my opinion, better or increase knowledge with increase in age as  I got education in school, college, and job and gain or improves knowledge from childhood days to the present time. I improves my knowledge with age.

Presently, I am a freelance content writer and write blogs in several fields including tourism, health, digital marketing, smartphones, economics, and many more.  Thus, I read about these things before writing blogs, which improves my knowledge in several fields.

Thus, increase or better knowledge with age as per my opinion.
