Hi Luciano, good to meet you too. Well there have been a few Korgs (including the MS-2000), one or two Roland boxes (like the TR-606), and I have fond memories of the Novation Supernova, and the Jomox XBase09. Right now I've cut down somewhat and am trying to focus on software, but I still own a lovely Elektron Machinedrum (kind of a little modular synth), an actual little modular system, a Microfreak, and a Yamaha Reface DX. How about you? As far as longevity goes, I think the best things are regular exercise and good sleeping habits of course, but there are perhaps some dietary changes we could/should make. If you don't have unlimited time for reading scientific papers yourself, a far better source of info than me on the topic are certain YouTube channels such as one I like called "Conquer Aging Or Die Trying!" Speaking of diet, is it easy to eat healithy there in Italy at the moment?
