Age/Weight increase, Slim Jim will not fit in philosophy I suppose.
Its not meant as disparaging, more fact. You will miss a lot of explores if you can't climb or worse can't fit between the bars of pallaside fencing. I'm not a skinny dude anymore but can make myself so, just breathe in hard.. it seems to work!
Effort always required, I admire how you guys move around getting into some of the damnedest places. Won't see what's in there if you don't try....
