Read and share it.* This is the *last secret you need to know about if you wish to live longer.
Control what you dream.
Now I'm not joking in here.
An unknown entity would knock at your door or your home's window in your nightmare, don't bother answering it even in your nightmare.
Because whether you believe me or don't but the person at the door or window will give you a simple scare to you in your nightmare, and you get scared with a heart-attack following it in quick succession.
If you're aged 50+, this might be a wake-up call.
Don't sleep alone, try sleeping each night with a kid who cares about you and can wake you up when they listen you murmuring, "Who's that at the door," in sleep.
Believe me people. Night time sleepy heart failures are a result of nightmares. That's for sure and avoiding delving in those nightmares is probably the only method to avoid death at an ancient age.
