Regulations covering scientific experiments on human subjects are strict. Subjects must give their informed, written consent, and experimenters must submit their proposed experiments to thorough examination by overseeing bodies. Scientists who experiment on themselves can, functionally if not legally, avoid the restrictions ① associated with experimenting on other people. They can also sidestep most of the ethical issues involved: nobody, presumably, is more aware of an experiment’s potential hazards than the scientist who devised ② it. Nonetheless, experimenting on oneself remains ③ deeply problematic. One obvious drawback is the danger involved; knowing that it exists ④ does nothing to reduce it. A less obvious drawback is the limited range of data that the experiment can generate. Human anatomy and physiology vary, in small but significant ways, according to gender, age, lifestyle, and other factors. Experimental results derived from a single subject are, therefore, of limited value; there is no way to know ⑤ what the subject’s responses are typical or atypical of the response of humans as a group.

In reality, objects do not conform to a linear lifecycle model; instead, they undergo breakdowns, await repairs, are stored away, or find themselves relegated to the basement, only to be rediscovered and repurposed later.
By their very nature, the concepts of maintenance and repair are predominantly examined from a process-oriented perspective. ( ① ) The focus in related scholarly discourse often revolves around the lifespan or lifecycle of objects and technologies. ( ② ) In this context, maintenance and repair are considered practices that have the potential to prolong the existence of objects, ensuring their sustained utilization over an extended period. ( ③ ) Krebs and Weber critically engage with anthropomorphic metaphors that imply a biography of things, appropriately highlighting that conventional understanding of the lifecycle of a technology, from its acquisition to its disposal from the household, provides an incomplete definition. ( ④ ) Additionally, objects may enter recycling or second-hand cycles, leading to a dynamic afterlife marked by diverse applications. ( ⑤ ) As such, the life of an object exhibits a far more complicated and adaptive path than a simplistic linear progression.
