Austin is no "kid". He is 29 years old. He is a grown man. If he was 17, I'd buy in to calling him a "kid". Not at 29 years old.
To put this in a little perspective, in the early 1960's at places like Lions Drag Strip, most of the young men racing then really were almost kids, being in their late teens and early 20's. If you were as "old" as 29, you would have been considered almost an old man.
