I heat with wood using 5 to 6 full cords per year. I store no more than 5 to 7 days' wood at a time in the basement and rotate it so none sits more than 4 or 5 days. I do not store wood in or next to the house outside of the heating season. Long term storage will most likely lead to bug problems and mouse problems.
I am 10 years older than you and went through the same thoughts a few years ago. I've made changes over the last few years to keep the work manageable. The first project involved eliminate having to move the wood down 13 steps. It involved removing 5' of my deck paralleling those steps, cutting a hole through the concrete wall, putting in a wood chute, and pouring a sidewalk to it along the space freed-up by removing part of the deck. There was a ready-made alcove to receive the wood below the chute but it contained the water pressure tank and water heater. So these were relocated to another corner of the furnace room. The existing basement stairs had a roof but I replaced it with a larger one covering the new sidewalk north of the stairs, the stairs, and a main sidewalk south of the stairs.
I had storage for 2 full years' of wood but built another 20' x 30' pole shed to allow me to store another year's wood plus the tractor with pull-type snowblower and other equipment.
My original wood storage is about 100' from the wood chute and on level ground so I could use my 2 wheeled hand cart to get it to the wood chute. The new shed is 300' from the chute with a fairly steep uphill section. My original plan was to use my pallet forks to move large pallets of wood on dollies to the covered deck and roll it to the chute. I experimented with that this year. It was just possible but I knew I would eventually wreck something on the house. So this fall I bought an electric hand truck from Princess Auto ($800 cdn). It works perfectly and can be moved all the way to the wood chute.

We have made other changes and will dream up more so that, given reasonable health, we'll go out of here feet-first when the time comes.
But, no, I don't think it is a good idea to store wood in your basement.
