(CNN) -- For Alex Zanardi, losing both legs in a life-threatening crash was only the beginning of a new chapter.

This year, the Italian racing driver, who has competed in Formula One and Indycar series, added two Paralympic gold medals and a win in the New York marathon's handcycle division to his career highlights.

Reflecting on what lies next, he says: "I have to tell you that the possibilities are not lacking in my life, and this is something for which I feel very lucky."

At school, Zanardi didn't compete in sports much, "because I was really fat as a kid."

After his sister was killed in a car crash his parents were eager to keep him off the road -- but they did allow Zanardi to race go-karts.

"I clearly remember that first day on the go-kart being the best in my life," he says.

Zanardi first raced in Formula One in 1992. After a contract with Lotus ended, he switched to Indycar racing, ultimately winning two championships.

In America he became a popular driver, making a signature move out of performing post-race donuts on the track, and earning the nickname Latka (a reference to a character in '80s sitcom "Taxi").

The crash

In 2001, Zanardi was leading in a Champ car race at Lausitzring in Germany, with 13 laps to go. But as he emerged from a final pit-stop, something went wrong.

"I lost control of the car in the acceleration lane, spun around and basically ended up ... a sitting duck in the middle of the racing line."

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 3, 1 1 3, etc. are all valid factorizations of 3.

The property of being prime (or not) is called primality. A simple but slow method of verifying the primality of a given number n is known as trial division. It consists of testing whether n is a multiple of any integer between 2 and . Algorithms much more efficient than trial division have been devised to test the primality of large numbers. These include the MillerRabin primality test, which is fast but has a small probability of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of January 2016[update], the largest known prime number has 22,338,618 decimal digits.

Once upon a time there was a cowgirl named Callie. Callie was the most beautiful cowgirl in all the land. She rode a beautiful horse. Her horse was brown. There are plenty of other horses. There are black horses, white horses, and red horses, but Callie's brown horse was the only horse in the world. Callie lived in a beautiful house with her husband. Her husband's name was Henry. Henry was a very good farmer. He grew tomatoes. His neighbor grew corn, potatoes, and bananas. His neighbor's name was David. David had a son named James who played in Henry's field. One day James fell and Henry almost ran him over with his horse. It was very scary. James was very careful when playing in the field. His dad told him never to play in the field again and he listened. Henry was very sorry for scaring him and sent him a basket of tomatoes.
