    The problem is that a phage is highly selective which means it will kill some bacteria while not other bacteria and they could kiĺl good ones as well and leave the bad bacteria. So I think more search is needed

    And for a minute, I thought humans were going to cure the over-population problem by making super-bugs. Sadly, humanity is bullet-proof.

    The problem is, we humans, we take more and more antibiotics for less causes (says on the video), but antibiotics don't kill 100 % of all bacteria. And the ones that survive, they learn and make counter ways to resist antibiotics. Like an evolution. We should not take antibiotics unless gets worse. The best way to survive even more stronger bacteria infections is to let the immune system do its work. So it can learn about and make more powerful (weapons). If the infection doesn't stop in maybe 2 days, then yes you should take antibiotics to give ur immune system a (hand) to defeat the infections. This is just my opinion.

    Okay easy on the visualization there I'm trying not to vomit out MY insides here Also would just isolating an environment from bacteria entirely keep someone alive? Would we be able to escape them in the vacuum of space? Because although they're small and everywhere, on Earth That doesn't mean they can just appear anywhere Besides that It's never a bad thing to be a little Mysophobic Infact maybe that'll be my new years resolution

    The problem with medicines and new cures is the monopoly companies that have sunk their teeth deep into politics and the health market . I believe that health system should be seen as a market but should be controlled half by private sector amd half by the government.
