human construction? Depends what you mean by construction, but I would say no (except under a very broad definition of the term)
an activity? Not really an activity as we would usually use the term (although, again, maybe yes under a very broad definition of the term).
In both cases I think that the most helpful answer is probably no.

I am going to Thailand for a week tomorrow (for those who don't know, the reason why is here). We are staying somewhere new, and so I do not know if I will have easy connection to the internets. If I fail to respond to questions here within 24 hours, someone else should take over.

[CdM] Thank you. Hope the trip goes well for you all.

[Chalky, Iroul] Thanks. Of course, if nobody posts any questions, it will be a non-issue. :-)

Looks like CdM is in an internet-free zone - anyone want to do a quick interim one to see us through until he returns?

Having just found the internets again...
an emotion? no
located in a particular place? yes, it was.
saying or proverb? no.
fun? no. (except, just possibly, for one person, but probably not even for him)
generally regarded as positive? definitely not.

Sorry for trying to kill you off prematurely.

[Irouléguy] That's a fine guess you've made there and I was going to ask the same question, but then - He died to 'save' us all - so that might be constrooooood as a positive result :-)

Generalising Raak's question.
