First Female Doctor
In the period known as the "Old Kingdom" in Ancient Egypt, from 2600-2100 BC, all professions were open to men and women, including the clergy, business, and medicine. In fact, records show that there were more than 100 prominent female physicians in Ancient Egypt, with Peseshet as their director. She was known as "lady overseer of the female physicians" - although it is not established that Lady Peseshet was a doctor herself and even if she was she was not the first known female physician. That title goes to someone who practiced medicine almost 100 years earlier: the world's first known female doctor was Merit-Ptah (2700 BC).

2. Supertall skyscraper is defined as a functional and habitable building with height over 300 m, as the number of buildings exceeding such height is considered very low around the world. The change to the height from 300 m to a number much higher (like 400 m) to be placed in 'supertall' category would be suggested in near future when more and more supertall skyscrapers are being built.
3. Burj Khalifa which is the current (in 2011) world tallest completed building stands at a height of 828m, which is almost double of the minimum height for a specific building to be placed into top 10 world tallest buildings' list. (current 10th place goes to Trump International Hotel and Tower at a height of 423m)
4. Despite Burj Khalifa is the tallest building, Shanghai World Financial Center still hold the record of world tallest observation deck at a height of over 470m at 100th floor. Burj Khalifa just took the title of world tallest OUTDOOR observation deck at a height of 452m at 124th floor.
