This is true, though sometimes one may unintentionally come across as a “know it all” (I know this from experience). Having an unending number of hobbies and the philosophy of “there is no such thing as useless knowledge”, just leads to accruing knowledge on a wide breadth of topics and surprising depth on some of the more esoteric.

I can tell you about some of the practical efforts required to safely raise chickens in the PNW (free-range, in a yard, or chicken tractors), several forms of metal casting, basic garment construction, luthiery, gardening, archery, industrial microbiology, and a number of other things. My former boss would often ask if I knew anything about a given unusual topic that came up in conversation, just to see if he could find something that I didn’t have any knowledge or experience with (really old programming languages like COBOL were among the winners). Now, I’m currently really into digital electronics, so, I’m shopping around for an oscilloscope and other equipment that would allow me to reverse engineer some of the newer protocols.
