12. Only the Red Pill or the Blue Pill Will Work

Your genetics play a big role in how drugs affect you because of the receptors in your body that the drugs target. It’s been found that about 90% of drugs only work for about 30-50% of people. Many people have experienced taking a drug that doesn’t work for them, showing how hard it can be to find the right one.

In the future, doctors might use genetic tests to see which drugs will work best for each person. This means you wouldn’t have to try lots of different drugs to find the right one—you’d just get tested, and your doctor would know which drugs are most likely to help you.
