A beginner athlete is like a baby snake, they're more dangerous because they don't know to control anything.  They also don't know any better and assume they have it all figured out! 

This whole episode is dedicated to the concept of training age.

Chronological age is simply how long you've been alive.  

Biological age is a measure of how the biological aging process has impacted your body. It can be defined in terms of what researchers call frailty indices – in what areas does your body work less well today than it did last year, or a decade ago?

Training age is the cumulative amount of time you've spent training for a particular sport. It refers to a cumulative workload (and skill level) built over the years and years of consistent training.
