I think I could probably do it, leaving aside food, toiletries and presents.
I'm in my late 50s and have enough clothes and shoes to last the year, especially if I manage to lose some weight which would allow me to wear lots of clothes in my wardrobe that I currently can't!
I don't buy any books now, except as presents, as we use kindles.
However, if any electrical appliances broke, I would replace them with new ones. My 'overflow freezer' in the garage is on its last legs, I think, as it's very noisy. However, it was bought in 1979, so it's done pretty well! The only other household item I'm thinking about buying new this year is a duvet to replace our current one. That's not as old as the freezer, but it is over 25 years old.
