I want to work until I die

After the shock, what exactly do I mean by that? ​ The following: ​ Being financially free at 55 or 48 to just lie around lazily every day or travel the world will not fulfill me personally. I often see that life goes by quickly among pensioners who don't have a hobby. I can sleep well now, my income will always be there as long as the world turns and Germany exists... The house is already there, now it's invested but for what? I honestly do it for fun.
