I just turned 60, and am thinking of getting my medical back and getting current again, though this time in weight shift trikes. I'm a healthy person, take no medications, have never been diagnosed with cardiovascular problems, blood pressure around 110/70, normal weight. About the only issue I can think of is that I had radial keratotomy done about 35 years ago, and now I wear contact lenses to correct my vision, last time to 20/20 in each eye separately, and that I'm developing a cataract in one eye. Since I'm way out of currency, I'll need a lot of dual to both learn to fly a weight shift aircraft and to get back to current, probably enough to get me to where I could add the weight shift rating to my private airplane certificate. To do that, I'd need my medical back. I hear older pilots talk about the difficulty keeping their third class medicals, but since I have no health issues, should I expect difficulties getting mine?
