No, Philip, "we all" don't. It isn't just that making such a sweeping statement is insulting to the extraordinary diversity of all of us who travel.
It disregards the fact that a great many people do nothing of the sort. I have indeed trekked the Andes, not necessarily half-naked but I sure have been tired as hell. I've also hiked huge mountains, ridden horses in the last of the great horse cultures of Middle Asia, and done the kinds of extreme adventures and sports which leave someone completely and utterly spent, and transformed. All after sixty. I wouldn't set foot on a cruise or stay at a resort for any money. Give me a tent, a guide, some kind of furry transportation and I am good to go.
I go for four to six weeks at a time, immerse myself in the culture. There is no better education.
I don't have an Instagram account. But I do write prolifically about the deep and important lessons that true adventure travel teaches: the humbling parts, the embarrassing parts, the painful parts.
That said I agree that tourism in many ways sucks, and as someone who does pretty extreme travel regularly, what I see is a raft of idiots in search of Instagram photos with no regard for the environment. Or for the inherent and exceedingly valuable lessons in witnessing extreme poverty, the real effects of climate change all over the world, all those things which true travel could do but most allow those lessons to wash over them without any kind of transformation taking place.
You have every single right to your take. There is no WE ALL. Each of us heads out differently. I decry many of the same things you do. However when you make such a statement you sweep everyone along, and that's just rude to Dear Reader.
If you find travel boring as hell I would look carefully at your travel companion. He looks back at you in the mirror every day. Boredom is exceedingly good for the brain and the soul. Research it. I did. It's remarkable what happens when you take the time to be bored. Nobody and no place owes us constant entertainment.
Some of us are born wanderers, Philip. I am one of those. I started wandering when I was old enough to stand. It's in my blood. It's not for everyone. What you're describing is tourism, not travel. There is a key difference, and that's why there is no WE ALL. There are your opinion, your experiences, unique to you, from which you can pontificate only on your own experiences. But you don't speak for anyone else.
