Physical enhancement refers to the use of various methods to improve the human body's capabilities, appearance, or performance. This can include activities like exercise, nutrition, and the use of technology or medical interventions. Common examples are strength training, dietary supplements, and cosmetic surgery, all aimed at achieving better physical health or aesthetics. In recent years, advancements in science and technology have led to new forms of physical enhancement, such as gene editing and biotechnology. These innovations raise ethical questions about the limits of enhancement and the potential for inequality in access to such improvements.
