&gt; Because you don&#x27;t risk bankruptcy by having a health issue, if you&#x27;re single it&#x27;s not a sausage fest, more laid back work (in SF it seems you&#x27;re bound to stay longer times at the office), greater tourism choices (a short trip away) and probably still cheaper than rent in SF even if we&#x27;re talking London<p>We have another reason right in this very answer: People in SV are willing to take more risk and sacrifice. Sure there are chances one may be bankrupted because of a health issue. Sure there are fewer entertainment choices. Living in SV may not be an ideal lifestyle for many but it has attracted a lot of adventurous mind from all over the world, who together conjure up trailblazing ventures.
