Well, that's the trick, isn't it: to 'seem' to know? 😀
Seriously, I'm just an elderly nerdy male who never amounted to much, but who has never stopped testing the limits of my ability to understand and to absorb (sometimes useless) information. I read tons, watch videos, and then try to use what I have learned. If I find it useful, I pass it on when I can. So, nothing special about me.
