love how even the less shit search engines (ie: not google) are starting to return mostly poorly sourced or suspicious junk, often undated and thus useless, sometimes unauthored. And the closest to something actually answering your question instead of "seo optimised" (ie: spam) click traps is quora or reddit, where people will just say some shit that sounded like they knew something
"how much could a typical adult carry"
"well most people could carry 15Kg* in one hand without any issue"
uh... are you sure
