Your post Leo fits well with your Andretti quote.
I don't know if it's an acquired taste or the result of a personality trait - it might be a chicken or egg first kind of question.
There was definitely a "type" of person attracted to the work. A former co-w*rker, who was also in management, had a ritual of celebrating his birthday by going out to the most dangerous dope corner he could find and making an undercover bust just to prove he could still do "it". It's not that we weren't afraid, it's that we didn't want to be ruled by our fears. One guy overcame his phobia of spiders by buying a pet tarantula.
I'm going to have to touch base with some of these guys and see how they deal with it in retirement.
After retiring I was somewhat tempted by the money that government was throwing around at people like me who were willing to go to dangerous places. There was a moment during a trial run when it was really "exciting" and I started hating myself for being irresponsible and getting killed just as my family was celebrating the end of my career.
A few years into retirement I find that I'm struggling with this. It was easy to be risk averse when my boys were younger, but now, especially with the oldest, it's not that easy.
I'm working on trying to understand the difference between pure fear-driven adrenaline thrill, and fun things that also happen to have some degree of danger. The oldest kid is in his peak macho inspired thrill seeking age and I'm hanging in there with him, but there's a lot of conflict going on. We went snowmobiling, something neither of us is experienced at, and we did go off the trails quite a bit. There were a few times I got concerned for him and that protective vicarious-fear came back at me as I realized I was in the same situation. I found myself backing off on the throttle (something I'm not used to doing) and telling him to do the same.
He thinks he's invincible, but I know he's not, and that reminds me that neither am I. So I have found that caution, fear, responsibility or whatever, is dictating my choices more than I'm used to.
There are risks associated with any activity, but I worry that I've become overly cautious of the risks associated with any activity. Yesterday, while standing in line at the airport I found myself close to a guy about my age who was in a wheelchair. It was a pain for him dealing with the TSA and I started thinking about all the travel I have planned and how difficult it would be to try and do that in a wheelchair.
And I was nursing a sore knee caused by getting up wrong while practicing free fall in a wind tunnel, and I started getting nervous about skydiving. I had this whole conversation with myself that eventually led to a temporary stalemate with the voice that said "be careful" countered by the one that said "don't let fear keep you from enjoying life."
