I had no idea A tree could live so long, i guess we will never know how old it would of lived.

I couldn't get the hole story, to much info.

"In 1964 a geology student called Donald R. Currey came to Wheeler Peak to study ice age glaciers, partly by collecting tree ring data. Using coring tools, he identified trees over 4,000 years old.

When his coring tool jammed inside a massive tree, he asked for, and received, permission from the US Forest Service to cut the tree off at 2.4 metres above the ground and keep a horizontal slab for study. When this slab had its rings counted, it turned out to be over 4,844 years old. Later cores taken closer to ground level by dendrochronologist Don Graybill showed it to be 4,862 years old - the oldest living thing ever discovered."

I wonder did he think to ask for a new coring tool, or
did he just want to cut the tree down?

Very interesting comment, Thanks.
