I have silver, and I love it. I'm convinced that it is a good keep for the future, even distant future (we need to leave our grand-grand childrens something to remember us, isn't it?). The future looks bright, as lot of silver is used in solar panels (has the best thermal and electrical conductivity). And silver is also used for weather control - Silver Iodide is used to seed clouds to produce rain. One day when we will have weather control on planetary level, they will also need silver, isn't it?
