Surfactant is a complex substance containing phospholipids and a number of apoproteins. This essential fluid is produced by the Type II alveolar cells, and lines the alveoli and smallest bronchioles.
My friends and family say I am obsessive about the subject. Shakespeare had three children. Susannah was born in May 1583, six months after William married Anne (so Anne was pregnant at the time of the wedding). Two years later (1585) the twins Judith and Hamnet (girl and boy) arrived.
At eighteen, he married Anne Hathaway, a woman seven or eight years his senior. Together they raised two daughters: Susanna, who was born in 1583, and Judith (whose twin brother died in boyhood), born in 1585. Little is known about Shakespeare's activities between 1585 and 1592. Robert Greene's A Groatsworth of Wit alludes to him as an actor and playwright.
