I've been hiking since 14 years of age. In my youth I did a lot of backpacking but as I age I only do day hiking. Typically somewhere between 7 to 11 miles in a day and typically with a good amount of elevation gain/decline. I love the mountains! You can see by my avatar picture that I am a skier, too. I have been skiing for 49 years and still enjoy the higher elevations and big mountain skiing. I got 23 ski days this year, the final 2 were just last week. And of course, at Mammoth Mountain. I also fish for pelagic species (tuna, yellowtail, dorado). Though that is at sea level (not the mountains) it is most certainly the outdoor lifestyle and more experiences of this beautiful planet. And I get to stuff my freezer with some amazingly delicious fish😋
Sorry to ramble on about myself. Bottom line, though, whatever you prefer to do in your spare time, @whart is absolutely correct. Chill out and get outside of yourself. Just get outside and experience the world around us. It's awesome! And it provides such marvelous memories.
