I have been a member for a while, but have been inactive. I was certified back in 1999, but have not dive since then. I have been thinking about getting re-certified, but have a few worries. I now wear contacts and am worried that when I have to clear my mask I will have issues with my eyes. I also have not done much swimming, I use to be an avid swimmer and unsure if my lungs and body ca handle getting into spending so much time in the water.
