What are 3 products that make your day to day life easier?

That`s such a great topic to disscuss, especially nowadays. I`m sure about a few hundred years ago the list of those things, that make your life easier from day to day included such things like, you know, horses or cows, or the pickaxe and so on. Nowadays there is a lot of things people do that got diversificated a lot. Like, you know, some people are still working with horses or cows, but another part is getting paid for doing more intelectual jobs, like, you know, IT for example. Personally for me those 3 things would be: 1. My laptop, that`s for sure. I can`t imagine my life without that. It helps me with work, it helps me relax after work. It is one of my greatest friends 2. YT music. World without music sucks. That`s really hard to me to live without a soundtrack of my life 3. Monetary system. Just take a while to imagine we still only do the trading operations to get something, like tomatoes to do a sallad for a dinner. I think it is the most underrated one, that people ever invented.
