A question for the brain trust

[squishy]

Ok so my cousins grandparents were very influential in getting me back into cigar smoking. They were comming through FL and stopped by for a bite and a smoke. We started talking cigars and they they went and grabed their travel humi to show me a few things. One of the sticks he showed me was one he said he has had for many years. Ok I tought I couldn't wait to check it out. When he showed it to me it looked like someone had taken powered sugar and dusted the cigar in it. It was covered in some sort of white residue. He was trying to tell me that this is how you know if a cigar is aged properly. My gut told me he was way off on that fact. But since he supposedly hast a vast am mount ok knowledge I didn't say anything. My question to you guys is this normal or is there something wrong there. Also what is that white residue on the 'gar???
