Yes Sir, welcome 'back' into the hobby - You'll quickly discover lots of good information herein and alot of folks, whom will readily assist and/or answer queries.

You sound abit like myself - Retired [going on 11 yrs, now] and got back into this hobby following a hiatus; Use to do alot of 'outdoor' stuff, but must admit have slowed down some, over the years. I still find 'building models' therapeutic and relaxing and now share it with Grandkids. I don't think I'll ever 'retire' from throwing-glue-and-paint when it comes to models/figures... And the 'researching a subject' is still one of the best things I've found within this hobby.

Again, welcome back - It's  fun!
