The inability to remember has long been considered a failure of the brain, but a new study has found that our brains are actively working to forget memories in order to retain the truly important information.
In fact, the study’s researchers believe the brain is not designed to keep memories intact, but its actual purpose is to only hold onto valuable information to optimize intelligent decision making overtime.
"It's important that the brain forgets irrelevant details and instead focuses on the stuff that's going to help make decisions in the real world," says Blake Richards, author of the study and associate fellow in the Learning in Machines and Brains program.
The new University of Toronto paper was published Wednesday in the Neuron journal. Paul Frankland, a senior fellow at CIFAR's Child & Brain Development program, who was also involved in the study, says,"We find plenty of evidence from recent research that there are mechanisms that promote memory loss, and that these are distinct from those involved in storing information."

Only one? I always dream I have two penises. I know exactly where the idea came from too. When I was very young and experimenting with masturbation, I rubbed it raw, fell asleep, and then I dreamed about rubbing my other penis which was not rubbed raw yet, and, according to dream logic, I must have two because there are two pockets in my pants. Ever since then, the double penises have appeared in my dreams.

Uncircumcised. When I was about 11 years old, I masturbated enough to make my foreskin swell shut, so that it was too swollen to roll it back. My parents took me to a doctor, who was unconcerned and prescribed an antibiotic cream in case of infection.

The doctor probably assumed the situation was normal for an 11 year old boy, since the glans and foreskin grow at different rates, at that age the foreskin doesn't necessarily retract.

Of all men, 30% have been circumcised; of all circumcised men, 68.8% are Muslim.
Traditionally, Muslims circumcise boys when they are 7-to-12 years old; this is also the same age for non-Muslims in the Philippines, where it is a bizarre tribal ritual, and African tribes tend to do it to older teenage boys. South Koreans, who picked up the practice from Americans, also do it to boys when the are about 10 years old.

I'm pretty sure neural network simulations don't generally simulate the effect of alcohol consumption. And I don't see how that dropout stuff you linked to is related to that.
Oh, and BTW, if you are forgetting things because of your alcohol consumption, it definitely means drinking too much alcohol.

The neural networks perform better if they randomly forget things they have learned during training. Try it while learning to play a song, etc. If you just keep playing the same thing over and over you will perform worse later. If instead you mix in other stuff and forget the exact movements, and relearn them, you will perform better. The same goes for studying. People remember almost nothing when they cram for one night for a single test.

Since evolution is not about how the first living organism came into being, but about how from that all species came, the complexity of the cell is in no way important for the question whether evolution is real. Evolution is compatible with the assumption that God created a single bacterium on earth, and that bacterium spread and evolved. Evolution is of course also compatible with the assumption that life came into being without intervention of a being from outside this universe.
Don't confuse things. Evolution is about the origin of the species, not about the origin of life.
