People You May Know from Facebook Stories on Vimeo.

Some may find Facebook's People You May Know suggestions more annoying than useful. Perhaps they're a constant reminder of a romance gone wrong or the mean girls in high scool you secretly wanted to friend, but who didn't give you the time of day.

Mayank Sharma, a man from India, credits the feature with helping him piece back his life after meningitis and fluid buid-up in his skull left him without memories. He tells his story in a video posted in the social network's newly launched Stories page.

"I lost 27 years of experiences," he says in the video (above). "It's the past who makes you who you are, right? So who am I?"

He couldn't recognize his family or his own reflection in the mirror.

Meningitis is a bacterial infection that attacks the thin membranes covering the brain and spinal cord. It can result in brain damage, or even death, if not treated properly.

Meningitis can also be caused by viral infections, drug allergies, fungi and tumors. Viral infections are the most common cause.

"Viral meningitis is milder and occurs more often than bacterial meningitis. It usually develops in the late summer and early fall, and often affects children and adults under age 30. Most infections occur in children under age 5. Most viral meningitis is due to enteroviruses, which are viruses that also can cause intestinal illness," according to the U.S. National Library of Medicine.

Most meningitis patients survive, according to the Meningitis Foundation of America, but they can suffer from emotional or physical side effects.

Most offen, these include problems with coordination, headaches, deafness, loss of balance, seizures, speech problems, weakness or paralysis, lack of concentration and memory loss, like in Sharma's case.
