    That would depend on how bright he/she is.

    And how mentally strong they are.

    Human society is highly overrated and most people these days are complete jerks and only think about themselves.

    I lived pretty much 50 years of my life without human contact and very much isolated from society so I could continue to do that just fine I think.

    The way I see it life is a constant struggle and that with or without human civilization.

    The lack of human civilization will be the least of the problems for the last person on Earth though because there will be many other dangers and difficulties for him to face and this time he/she will have to face them completely alone.

    Sorry, the OP question has so many variables, it would take a book.

    Bottom line, if a person became the "last" person on earth @ 30 and his natural life expectancy was 75, he/she would have a life expectancy of 45 years and then humans would be extinct.

    musing: I noticed that the largest organisms are generally at the brink of extinction and the ultimate advantage would go to the insect, which has a short but productive life, before it returns to the earth as potential energy for something else small. An excellent conservation of energy.

    Will natural selection favor low energy *adaptability* or high energy *technology*?

    I still believe Hellstrom was right in his prediction. Watch the Hellstrom Creonicle (YouTube)

    In my opinion being the last man on earth is already not a good sign. I mean how did everyone manage to die except me?

    Also this also raises an important philosophical (or maybe biological) question: Why is everyone else dead except me? Why am I the last human alive?

    Lets just hope that this terrifying fate will not happen to anymore, although it can happen.

    In any extinction, somebody has to be the last to go.

    You could have your own farm and raise/breed some cattle, chickens and a garden besides stored nonperishables. You could have pets and trained dogs to protect property. Also plenty of ammo/ guns for wild animals or dangerous strays. Bottled water would not run out but you could use a well or rain.

    Just do everything the old fashioned manual way. Use oil lamps, candles, firewood etc.

    Entertainment: read for life. Nature. Alcohol never goes bad

    Companionship: pets

    Ive had thoughts where i wished everyone was gone and it was just me when im in a hate people/ humanity mood.

    I dont think i would be lonely at all because all i would have to do is remember what it was like and annoying, breathe a sigh of relief but a bit scared at times maybe.

    Sounds like paradise except if you got injured, you could only help yourself.

    Agreed...Would the earth be a fit place to live on, cosnsidering what caused the death/elimination of all others.

    The last person would survive just fine if they wanted to. Plenty of resources, no competition. The sticking point would be advanced medical and dental care.

    What of the psychology of being alone for the rest of your life ?

    Yeah, life expectancy would I suggest, be somewhat lower than if he/she was living in a modern society.
    But again, the condition of the Earth/environment that saw the demise of the rest of the population needs to be considered.

    Sure the enviroment matters but ......

    No psychology of any lone person matters ? Even in a perfect enviroment, without Human contact , at all , would be tough to hold your sanity .

    In my case I had someone I like to talk to....myself.

    Mind you I would only go for a month at a time and you can go cabin crazy if you don't go outside.

    I don't think I would have any difficulty being the only person left.

    Keeping interested in stuff, drawing, gardening, building things, and above all astronomy kept me very happy.

    Well I have lived without net, TV radio and only two string left on my guitar and no problem.
    Maybe cause all my life I have had to fix problems for people so I really enjoyed my own time with no ones problems, time to think about everything and nothing.
    I used to party seven nights a week so I have had my fill I guess.
    I do not miss the net when in the bush cause there are many fn things to do... real things.

    Well River I now find I must be in the city to look after my father, who is older than me, and so not able to lead my normal life.
    I came here to keep up to date with science news etc and got to like the folk here and the cheerful chat.
    Also my legs are not good due to some problem in my back (an opperation prevented paraplegia ) but they are getting worse so I spend a lot of time resting as opposed to doing "real" things.
    This site and the astronomy one is the only meaningful interaction I have with humans most weeks these days. I don't mind going to the pub playing pool playing guitar with the boys its just my life has changed.
