not all polls are intended for completely randomised sampling.
this poll is created for people who have a shared interest in a media type, otherwise it wouldn't have any purpose here in the first place
having a computer or not has nothing really to do with what actually the options put forward in this poll actually realistically entail.
it's like me asking you whether you prefer harp beer to budweiser when more than likely you haven't tasted harp beer before because it's produced in west africa, it gives a false impression statistically.
people are making their own definitions of eternal youth and invincibility as they see fit and writing their answers accordingly when some of these parameters aren't what i feel are really associated with these states (or perhaps overlap or are more in tune with the other).
hence based on this, what we see in the polls may not be an exact representation of what is really meant to come across..
as for the percentage weights, i haven't voted so i don't get to see the values but there is hardly any polls on this website that have enough people participating in order for any significant trends to be found, studied and made concrete.
it's a light poll just to see any light trends. however people get on to vote has no bearing on the end result since it has no affect on our answers as no other questions are asked in conjunction with it.
