I’ve been building for 68 of my 74 years so you’re not alone. There are a lot of us “Older gentlemen” on here. My grandsons like to watch me build and ask lots of questions but don’t want to build. I keep trying though.
Welcome Paul!! That’s cool that you are getting your grandson involved. I am introducing my 9-year old son to the hobby as well and have him started on his first kit. Its the first thing he wants me to help him with when I come home from work. Much better than video games.
