I need to inventory my stockpile, but guesstimate I have 30 
or 40 500-gram bags of G&H, mostly Sliced Brown Twist, Sliced 
Black Twist, Dark Flake, Coniston Cut Plug, Rum Flake, and 
other traditional tobaccos of similar ilk, plus a few more 
pounds of twist (unsliced) and Curley Cut. 
Add to that maybe 30 pounds of tobaccos by GL Pease, C&D, and 
others, and I may have enough tobacco to last me as long as I
live.  I may live longer than expected, though, as my mother's
side of the family had a Great-Aunt that made it to 102.  I am
coming up on 75, and expect possibly 5 to 10 more years to
match life-spans of my direct paternal ancestors, from Charley
Beard b. 1792 New York downward.
I do keep buying a few pounds every couple or three years though,
as my top favorites are consumed and the lesser lights continue
to age.  After maybe 7 years or so the taste does tend to 
diminish in intensity, so that may need consideration.
