(Trying to revive the sub)

• Walk. I walk a lot... well not since the last few days since I broke a bone, but usually :p
• Public transportation. here in Paris we have a lot: buses, tram, metro, train.
• Taxi or Uber when we really have to. My spouse and I have not owned a car in over 20 years.
• We have also refused to travel by plane since the early 00s. Be it for personal or pro needs.

Walk has had the most crucial influence: it helped me get back into shape like nothing else did, both physically and mentally. A few years ago, I was not walking at all. As a matter of fact, I could barely walk a few meters before having to rest, my health was a mess. Nowadays; I will walk every single day for 8km or more.
