My DH was dx'd almost 30 years ago and has been mostly asymptomatic. He has been having some symptoms in the last five years, but they are not debilitating and he is carrying on with work and family without too much trouble. He cannot however do the kinds of things we did ten years ago that require a lot of stamina, e.g. long hikes or bike rides. But he can walk for up to about a half-hour comfortably, and more if he has the opportunity to rest.
DH sees an MS specialist and is on a high dose of Vitamin D every day. Our kids are also on 2,000 IUs/day of Vitamin D as according to the specialist, if we keep their levels at 50+, it will cut their chances of developing MS in half. We expose them to as much sunlight as we can.
There is a theory that MS is related to a Vitamin D deficiency and indeed, it is virtually unknown in temperate climates. Scotland, a very cloudy, damp country, has the highest rate of MS in the world. The Scottish government launched a Vitamin D campaign awhile back in an effort to help reduce the rate of MS:

The likelihood of MS is higher for a child born in the spring than for one born in the fall - the theory being that the mother's exposure to sunlight during pregnancy reduces the risk. So, if there is MS in your family (or even if not), take Vitamin D during pregnancy and make sure your kids have adequate levels of D.
