You walk through your grandfather's house one last time.
It has been three months since he drove off and left, telling no one where he was headed.
You look through his address book, searching for one of his old friends who still may be alive, someone who may know where it is he'd gone. Or if he would ever come back.
Defeated, you flip to the back. A yellowed slip of paper falls out. This, you think, may be something.
Don’t you know it’s dangerous to live below me? I’m the lowest of the low, at least in theory. You’ll want to excel, but this is no place to thrive Down here you’ll be lacking- little power, little drive. You see life at all turns, from up on the top But down beneath me, your life can soon stop. Don’t live beneath me, there’ve been many who’ve tried But beneath me they've stayed, and beneath me they've died. They thought there was time, but running on breath They could not go further, nor rise above death. Please go and live a life fulfilled Unless your end is truly your will.
The poem is not shy about its message of death, but its meaning is lost on you for a moment. Nonetheless, it seems grandfather did not heed the warning.
What is it your grandfather attempted to live beneath?
EDIT: I have added a tag to point more people in the direction of grandfather's folly. Many of these answers fit beautifully, but user1566694's approach is certainly a strong one.
