I'm the same age. But I am also guilty of old habits when attempting new frameworks or languages. For example, I always want to set up the environment with the least amount of "auto loads" of libraries etc. I do not use NPM. I still play around with new JS libraries by direct downloads from the official websites or Github and always use local copies of .js .css etc. I don't even connect to CDNs for fonts! I want to know all dependencies etc. I am paranoid like that. And this can be exhausting.
