My point is that, even though we might find even more ways to improve/modify our bodies, they will come with slew of risks that are just not worth it if you can achieve it naturally.
On another note, I feel like there is severe muscle inflation in media which would distort how fit a person should be. You really do not need to kill yourself in the gym or hop on a some reddit-approved juices to get very fit. Just gotta experiment and find a comfortable full body workout that you can do consistently, like you brush your teeth every day.
