It really depends on what you can .. There was a recent test on foods that were canned over 30 years ago that tested fine and ready to eat .. I was SHOCKED !! but meats and such I would NOT let go over a year ..
Most people enjoy doing tomato's because they are a quick process and get pretty expensive here in the winter .. I don't know where you are but I have paid 2.50 a lb for tomato's
I also do taco sauce and salsa ..I also do pasta sauce
Hot peppers for hot sauce and cucumbers for pickles .. all these are a hot water bath process so you don't need any real special equipment.
I would put in even a really small garden and if you like it you can make it bigger and or if you dont like it you can always plant grass in the fall
Most of the gardeners on my website are men of your age .. most can ..
