So, if you are already weak, the battle may be too much for you to bear.

It appears that what doesn’t kill you can sometimes make you weaker. Just like a country under attack switching into a war economy, when you become sick, your body is forced to reroute energy and resources into your immune system. This can be very draining, especially if you are already weak or suffer from chronic illness. The damage caused by an infection, combined with the collateral damage caused by immune cells, can be too much for your body to handle. Having a serious infection can cause many tiny wounds and holes in your organs. Your body works to quickly close them up with regrowing cells and collagen, which is a sort of organic cement that gives your tissue structural integrity. The result of this is a scar, which is different from the original tissue and can’t do the same job. Scars on your organs can make them function less effectively, and this damage can be permanent. However, there is a way to train your immune system to avoid this damage: vaccines. Vaccines pretend to be a disease and train your immune system to be ready if it ever shows up for real. This is much safer than relying on natural immunity, as getting a disease to become immune means going to a “nature dojo” where you train with real weapons and there is a risk of permanent damage or even death. Vaccines are often better than natural resistance when it comes to immunity, as they are engineered to engage your immune system in a more effective way. However, they are not infallible, and may be less effective in certain cases, such as if an enemy mutates quickly or if your immune system does not respond well to the vaccine. Vaccination is still one of the best tools to strengthen your natural defenses.

In the long run, humanity may be able to overcome disease altogether. Until then, it is important to take care of ourselves and others to keep ourselves healthy. Additionally, climate change is a major challenge for our generation, and there are many ways to take action. One way is to work with Wren, a company that helps offset carbon emissions. By visiting their website and answering a few questions, you can find out your personal carbon footprint and offset the rest with a monthly subscription. Wren supports projects that plant trees, protect rainforests, and remove carbon dioxide from the sky. They also have a project called Refrigerant Destruction, which permanently destroys containers filled with harmful gases that contribute to global warming.

To take action, sign up through wren.co/kurzgesagt. The first 200 people to sign up will have the first month of subscription paid for by Kurzgesagt. Additionally, Kurzgesagt has many products available in their shop related to the immune system. All of these products are designed and produced with care.
