When I was in America, I met an old man who was 83 years old and his wife passed away. He swam alone for nearly 20 years. If he didn&;t walk slowly, I thought he was only 60 years old. He was wearing a yellow outdoor suit, and the letters on his shoulders attracted me. He was carrying a dark red hiking bag and wearing a brown hat. Later, I found a suit of the same style, and I thought this old man who swam alone was really cool. The courage of the elderly who travel alone in Denari National Park, Alaska, USA has multiplied with the expansion of their journey. They always have to take the first step. After retirement, they plan to travel far away. At first, they are excited. The preparation time is very long, and the tickets have been bought long ago. They are afraid of missing the day. After repeated confirmation, things have increased and decreased. What should we do if the weather is hot? Take a thin one. What if it&;s cold? Bring a thick one; Do you want two pairs of shoes? Do you want to bring medicine? On the day of departure, the mist cleared in the morning, and you came out from home very early. You wore the newly bought leisure outdoor clothes, and your shoes were not very suitable. The straps of your backpack were tight and loose, and there were people who got up early in the community. You passed by and went out alone. It was a bit like going out for the first time as a child, and your mood was a little different. You took a bus or took a taxi to the airport or train station, and found that you hadn&;t gone out alone for a long time, so you didn&;t have to change the high-speed rail ticket. On the means of transportation, I look forward to my destination along the way. I have downloaded a lot of software on my mobile phone and saved a lot of raiders. How can I get there by car? Ignore the black car? Where to go first? Where can I find something delicious? Where is a good place to live? How to get to the scenic spot? You don&;t have to take a small traffic in the scenic spot, because it&;s not far to walk; What are the unpopular attractions? Wait, and so on. This is the first time for you to go out. After about three to five times, the things in your backpack are getting less and less, and you are becoming more and more casual when you leave. You used to arrive at the station or airport one or two hours in advance, but now you are almost stepping on it. When you come out of the community, your mood is not so different. It feels like you are getting more and more courageous when you go out to buy food at the farmer&;s market, or even taking part in outdoor crossing, or going abroad alone. When I get home, I just look at the map, draw a range and prepare to go next time. The shoulders are covered with fur, the shoes are getting softer and softer, and there are only one or two clothes, but they are comfortable to carry and wear. At this time, it is not the courage to dare to step out of the door, but how long are you willing to stay at home? Is it cool for retired people to travel alone? It&;s cool that there&;s no calculation of domination and flattery, no business entertainment, no need to watch mobile phones, no need to think about those things in your head every day, no need to write or read reports at your desk, no need to worry about this and that, children grow up, grandchildren don&;t have to take care of themselves, people quietly relax, their eyes are clear, firm, and their personality is kind.It&;s the coolest time to see the color, to be indifferent, to be simple, and to have no desire. The so-called nothing is God. Why do we sometimes feel that someone is particularly comfortable? Because he has reached such a state, he practiced to be cool instead of playing cool when he was young, just like the old man who swam alone for 20 years in America. Slowly, what&;s the hurry? If you like traveling and retire, you can go for at least 15-20 years. Take the first step bravely and turn yourself into a cool old man with high quality of life and beyond. Destroy me, shape me, be original.
