Days before his death, Leonard Nimoy reflected on life and memory in a message posted on his Twitter page.
The tweet, sent Feb. 23, seems even more poignant now in the wake of his death Friday at the age of 83.
A day earlier, he sent another tweet featuring a work of poetry:
Nimoy, best known for playing Mr. Spock on "Star Trek," died from end-stage chronic obstructive pulmonary disease. His tweets were often signed "LLAP" for his character's famous phrase, "live long and prosper."
