Lina Medina (born September 27, 1933, in Ticrapo, Huancavelica Region, Peru) is the youngest confirmed mother in medical history, giving birth at the age of five years, seven months and 21 days.

Born in Ticrapo, Peru, Medina was brought to a hospital by her parents at the age of five years due to increasing abdominal size. She was originally thought to have had a tumor, but her doctors determined she was in her seventh month of pregnancy. Dr. Gerardo Lozada took her to Lima, Peru, prior to the surgery to have other specialists confirm that Medina was pregnant. A month and a half later, on May 14, 1939, she gave birth to a boy by a caesarean section. The surgery was performed by Dr. Lozada. Her son, weighing 2,700 grams or 5.92 pounds, was well formed and in good health. Child and mother were able to leave the clinic after only a few days.

Does classical music make you smarter?

On One Hand: Playing Enhances Learning.

Learning to play classical music increases spatial development when instruction begins early in life. The Clearing House on Elementary and Early Childhood Education states children learning to play classical music enjoy benefits of heightened spatial-temporal and arithmetic skills for up to two years after instruction ends.

On the Other: Listening Has Limited Benefits.

Listening to classical provides temporary benefits such as relaxation and enjoyment but no long-term developmental benefits. The Society for Quality Education states sensory skills will develop with or without listening to Mozart or other classical music.

Bottom Line

Listening to classical music produces temporary benefits, but researchers fail to determine long-term benefits. Learning to play classical music provides long-term benefits for children younger than 7 years old.

Do right handed people live longer then left handed people?

A study published in 1991 (Coren S, Halpern – “Left-handedness: a marker for decreased survival fitness”) claimed that left-handed people’s lifespans are shorter than those of their right-handed counterparts by as much as 9 years. The authors suggested that this may be the result of left-handed people being more likely to die in accidents as a result of their being clumsier and less equipped to survive in a right-handed world. Many subsequent studies have shown no evidence that left-handed people have reduced longevity compared to right-handed people.
