life starts at 0

it's a line 

negative positive

usually as the negative increases the positive increases equally

if you are on this this or this

    it limits the number on the line for how far you can go

-60 0 +60

buuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuut

    if you use one of those this

    -60 0 +60

    turns to -4 0 +4

and you could have -1000 0 +1000 built already

which causes others to reach levels you already invented or areas you already reached

and old info

appear as new info

but also get new info too so that's cool
