The answer is: maybe.
The majority of the world's population can be considered "lactose intolerant"--estimated at around 70%. It is actually only those of an European ancestry are, on average, much more lactose tolerant.

Lactose intolerance often begins only in adulthood.
All newborns are naturally lactose tolerant. Why this is, is simple: an enzyme "lactase" is needed to help break down the "lactose" present in milk: whether it's human breast or cow. As we age, lactase production decreases gradually among that 70% majority. Why? In many parts of the world, dairy products were only (relatively) recently introduced by Western society and were never previously consumed. Evolution. Europeans, continuing to consume lactose after breastfeeding, had need for continued lactase production. Many non-Europeans did not. The same reason why Asians have epicanthal folds, Africans have greater melanin concentration in their skin, etc. etc. Suiting our environment is all.

And lactose intolerance isn't absolute! I can comfortably eat a few ice cream sundaes, glasses of milk, etc. I'd say, for me, my limit is about a half-gallon of milk over the course of a day or equivalent. That gets my stomach churning. Hope this helps.

some causes of lactose intolerance are well known. Primary lactase deficiency is a condition that develops over time. After about age 2 the body begins to produce less lactase, though most people will not notice symptoms until they are much older.

Secondary lactase deficiency occurs when injury to the small intestine or certain digestive diseases reduce the amount of lactase a person produces. These diseases include celiac disease, inflammatory bowel disease, and Crohn’s disease.

Researchers have identified a genetic link for lactose intolerance. Some people are born with a likelihood of developing primary lactase deficiency because it has been passed to them genetically (inherited from their parents). This discovery may be useful in developing a diagnostic test to identify people with the condition.

so not really

Not all the facts are in on this one, but it would appear that lactose intolerance is most often (not always) caused by changes in the digestive system related to age.

no. lacotose intolerance is an inability for your body to break down lactase (the sugar in milk). stopping milk will not cause this. if you dont drink milk make sure you are gettign enough calcium from other sources, either a supplement or through food.

No, you wouldn't. I have never been a milk drinker and I can drink it if I want to. I don't even drink it after finishing cereal, it's just yucky to me.

I take a calcium supplement so I won't get osteoporosis later on in life.

No you don't choose weather or not you're lactose intolerent or not. You either are, or aren't.

No...but you need the calcium so I would rethink giving up milk.
