Points to ponder

If you could un-invent something, what would it be?

If I could uninvent something, it would be preservatives. I miss the old days when we would go to the store every day or few days for what we needed to eat fresh meals. We still bake homemade bread, rolls, cookies, soups, etc from scratch at home and love to visit our local grocer or farmer for our fresh veg and fruits.

What about you? What would you uninvent if you could?
