Sultan Kosen - The Tallest Man alive The tallest living man officially measured by Guinness World Records (Guinness Book of Records) is Sultan Kosen from Turkey, with a height of 8 feet 3 inches (251.4 cm) tall. Sultan Kosen was last measured in February 2011 and found to still be growing.
As a general rule, adult males need 3.7 liters of water per day, while adult women need 2.7 liters per day. However, pregnant women should aim for 3 liters per day, and lactating women need 3.8 liters per day. The daily adequate intake of water is lower before the age of 18. From birth to 12 months of age, infants need just 0.7 to 0.8 liters per day -- which is easily achieved through breast milk alone. The daily intake increases to 1.3 liters from age 1 to 3 and 1.7 liters from age 4 to 8.
Mr Somani said all adults should aim to drink between two to three litres of water a day, while former stone patients should maintain a daily intake upwards of three litres to avoid recurrence.
