On the Importance of Remaining 29 Years of Age

by J. M. Haile

It is also <30, which somehow correlates with trust, at least according to Jack Weinberg, a leader of the Free Speech Movement at UC Berkeley in 1965: "Don't trust anybody over 30."

Anything that's invented between when you're fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you're thirty-five is against the natural order of things." [1] So, 29 seems a good compromise to keep things interesting.

There are 29 days in a leap-year February and nearly 29 days in a lunar month.

A town in California is named Twentynine Palms, Iowa was the 29th state to join the Union, and there are 29 states in India.
