He's definitely still no Captain Tightpants by any means, but as a fellow former crazy maker / fire performer, you never fully grow out of it, but you mellow out over time and take less crazy risks (in favor of calculated risks).
The tunnel generally feels safe, but I can't say the same for the methods employed in digging it.
Grinding some pipe with it in my hand? Yeah I got this.
Digging a tunnel that will have the cameraman and others in it, and might collapse the house of done wrong? That's worth some thought.
Some. Lol.
That reminds me of this greybeard that was helping us move some heavy machinery. "It won't hurt you!" as we have a 1400 lb top-heavy drill press dangling from an engine hoist. Um, yeah, heck yes that'll hurt you.
Wouldn't have gotten it into the uhaul in time were it not for him.
On the flip side, I don’t think he’s all that completely cautious either. For example during testing in the absurd salad knife belt video (which features a whirling belt of knives) from one shot to another a very large bandage appears on his arm (and is never acknowledged) which suggests to me that that thing was exactly as dangerous as it looked.
