I'm 49. I spent most summers with my WWII generation (and served) grandparents. I'm not the "Marlboro Man", but enough of that generation was put in me that I feel like I am compared to most of the younger guys I meet. There is a distinct difference.
As an 8th grade teacher, I often talk to my students about skills that they just don't get exposed to. For instance, the earlier mentioned changing of oil. I polled 350 students over the last 3 years with this question. I've only had 6 students that have ever been shown how to do it. My personal 8th grade children already change oil in our vehicles, change brake pads, change a tire, etc.
Last week, I had septic field problems at home. This week, my students got a 10 minute lesson on how they work (I teach Science). Most kids have no one having these conversations with them, and I take satisfaction in doing it. Before you take offense to my use of the word "most", unless you serve our youth in some capacity, you might be surprised.
These skills may not be essential in today's world. Maybe they will be paid enough in their careers that it makes sense to let others do it. But there is more to it than the physical act. Doing such things for yourself shapes your character.
All that said, I suppose I am between those generations and now have an RV with many comforts. I hope the "tough" guys don't look down upon me. For what its worth, I do everything outside of major issues myself. :)
