> It is a poorly and erratically manufactured product done in inconsistent environments. As we learn more about our bodies, we will regularly discover things that should be fixed or optimized. This is a poor model for understanding the human body. The body is a massively high dimensional chemical and physical system where there is no objective function that will maximize performance in all possible environments. Every new environment will have new challenges and a new objective function to maximize. The common denominator that reflects our last global optimum is our genetics and epigenetics, which has some randomness but is not at all erratic. Most bodily processes are some kind of trade-off. You can have faster metabolism but you will age quicker. You can have a strong type I immune defense against infection but you will be more prone to autoimmunity. You can have greater anabolism and become stronger but that will compete with catabolic pathways and increase the risk of cancer. Nothing is free. Medication is the same way. For people with a moderate or serious condition, any downsides are worth it, but there are always side effects. No bodily system exists in isolation.
