Quite a lot of scientists did&#x2F;still do this. Heck, there&#x27;s even a trope about it on TV Tropes:<p><a href="http:&#x2F;&#x2F;tvtropes.org&#x2F;pmwiki&#x2F;pmwiki.php&#x2F;Main&#x2F;ProfessorGuineaPig" rel="nofollow">http:&#x2F;&#x2F;tvtropes.org&#x2F;pmwiki&#x2F;pmwiki.php&#x2F;Main&#x2F;ProfessorGuineaPi...</a><p>But I suspect it&#x27;s slightly rarer for CEOs of science based companies to try this stuff out of themselves. Could be interesting to see what happens.
