Not an old geezer by any means, but I think mrclmind was by far the most experienced nose who did Youtube reviews. Unfortunate that he decided to take them all down for whatever reason.
By comparison to the average age of most of the Youtube reviewers, I could definitely be considered a geezer. I took my reviews down because I wasn't happy with the quality. I am planning on doing new ones though! Thank you very much for your kind words!
