McAfee says "I simply would like to live comfortably day by day, fish, swim, enjoy my declining years."
The off-beat McAfee answered what he claimed were reporters' questions during a live-stream Internet broadcast from the Guatemalan detention center where he is fighting a government order he be returned to Belize.
Police in neighboring Belize want to question McAfee in the fatal shooting of a US expatriate who lived near his home on a Belizean island. McAfee has denied involvement in the killing.
McAfee said Sunday he blacked out and hit his head earlier in the week after not eating and smoking "almost non-stop."
