Razors
Since man discovered razors could cut hair, we’ve been cutting slicing our skin open ever since. They were probably created alongside tissue paper to cover up any nicks the razors caused to our skin. Back in the day, you just had to swap out a dull blade with a fresh one while keeping the shaver for several years.
Today, we have disposable razors that are piling up in landfills and choking turtles in the ocean. You’re supposed to use disposable razors once or twice at most, but it’s not uncommon to keep them for weeks. You should consider making the switch to electric shavers if you haven’t already.
