Your no more abnormal than the millions of other collectors out there. Just go on eBay and look at all of the different categories that people collect from. Its absolutely mind numbing all of the things people collect these days and I am certainly no different. My father got me into collecting at a very young age and it just stuck. Being a collector has been one of the most consistent aspects of my entire life and I collect in a LOT of different markets. It seems like each year that passes adds something new to the list.
I currently collect playing cards (mostly limited edition decks, but I do buy the occasional regular deck here and there), comics (mostly golden age and silver age), original comic art, limited edition prints/lithographs, antique/vintage camera's & lenses, antique/vintage Kodak memorabilia, Polaroid SX70 camera's, 1:4 & 1:3 statues (mostly from Sideshow & Prime 1), replica weapons (mostly sci-fi related), space/NASA memorabilia, wildlife stamps & first day issues, art books & sketch books, vintage Belstaff & Barbour jackets, etc. I try and fund a lot of my collecting hobbies by selling as well as buying. For example, I purchased multiple bricks of all of Jackson Robinson's Kickstarter campaign cards like the Federal 52 Parts 1 & 2, Legal Tender, Independence etc. and sell them off over time to fund other purchases. I usually buy multiple copies of limited edition prints and sell off the other copies after they are sold out. I even started buying 2 of some of Sideshow's statues and selling the 2nd one off to help pay for the first one. I recently did it with Will Harbottle's Red Sonja Statue and it basically wound up paying for the statue I kept.
As for the humidity issue, your best bet is to buy Pelican's small silica gel canisters. Here is a picture:
They are 4 inches long by 2 inches wide and 1/2 an inch thick. You can find these on Amazon as well as lots of other sites as well. Just google "Pelican silica gel canister" and you will get plenty of options on where you can buy these. The great thing about these canisters is they have an indicator right on the top (the small round thing in the middle) that changes color when it becomes saturated with water. They literally last forever. Once it gets saturated all you have to do is stick in your oven for a 2 hours at 250 degree's and its good to go again. I literally own about 75 of these canisters. I'm a professional photographer and I keep one in all of my camera bags and cases, plus I keep them in various boxes with all of my various collectibles. As long as you use these and you keep an eye on the indicator, you won't have to worry about humidity damaging whatever it is your trying to protect. And there are larger sized canisters you can buy for larger area's, like to put inside cabinets. I have a couple big one's in my cabinets where I store all my photography negatives. I have been using these canisters for over 20 years and they really are amazing.
