Why did I buy a bicycle?

I have already commented in my previous post, at my age I still have many concerns, one of them came to me a few months ago, because I wanted to remember those moments of my childhood where my worries were almost nil, I just needed to know that I made the word plan well .
I wanted to buy a bicycle that was like the one I dreamed of having in my childhood, but checking my portfolio I realized that my expectations were still very high after so many years, so I opted for a much simpler one but still being to my liking. No doubt I do not regret at all, I saved a lot of money on gasoline, I lost a few kilos and if it was not enough, now I earn an extra income !, they are not millionaire profits, but it is quite rewarding the work I do , because I leave a little of the everyday, I know very good people and I have a good time in the afternoon distributing food.
I have also thought a lot about the environmental aspect, although I am not very passionate about the subject, it is good to know that you contribute a little to the care of the planet, which has motivated me to take more ecological habits than I had before. Fortunately I live in a very quiet city and with a fairly clean air, it would be a nightmare to become those smog monsters that I have so much fear of.
I would very much like to have your experiences told by those who have a bicycle!
