If you are Edmund Hillary, then knock yourself out. Climbing Everest today isn't pushing the limits of humanity. It is no more admirable than playing Russian Roulette.
It sounds like we're implying we should all either do something off the scale epic (like Hillary, or Felix jumping from space, or Amundsen) or we should all do mundane stuff for our entire lives.
I personally think people need to get out there and have their own adventures. For person 1 an adventure might be getting outside their comfort zone and talking to a stranger they find attractive in their apartment building. For person 2 adventure might be doing a 5 mile day-hike in a National Park, where-as for person 3 an adventure might be sailing around the world.
The fact all of those have been done before doesn't diminish the scale of the adventure for the individual, nor does it give us any right to comment on whether we think it's a worthy pursuit or in fact "adventure" at all.
Everybody needs to do what's right for them, with the level of planning and preparedness that's right for them.
