Unexplained was where his information came from. Perhaps he made it up. Maybe his imagination ran wild. It ran away from him on Chavez.
On October 19, when confronted outside his home and asked to explain, he said, "No, no, no, no, no. I'm not doing interviews." Apparently he wants things quieted down.
Pay close attention to what Castro family members and others close to him say. Health is very personal for most people. They prefer not having reports about it made public. Their right deserves to be respected.
Castro family and Cuban government officials deny reports about Fidel's impending demise. On October 19, Havana's Foreign Ministry used Twitter to denounce the latest one.
It was falsely attributed to Cuban Foreign Minister Bruno Rodriguez Parrilla. Misinformation under his name pronounced Castro dead. Whoever sent it got Parrilla's Twitter handle wrong.
All that's known is that Castro's been less visible recently. That alone proves nothing. Speculation without facts is more disservice than helpful. Believe nothing without corroborating evidence.
If Castro is alive and well, perhaps he's slowed and taking a break. He or those close to him will explain in due time as they see fit. It's their right. Until then, assume nothing circulating online or reported by scoundrel media.
