What term retirement usually denotes to is, to stop working. People often don't like job, so to retire usually tends to be on top of the list. However, if one likes what he does, he will do something similar to pass the time even after retirement.
Now, I'll be honest, I dunno what I am driving at but I wanted to spark topic about retirement. Now, you go,
I think retirement doesn't really mean that you'll stop working. It means that you'd retire from your corporate job but you'd still do things that you've used to do whether they make you earn money or not. It's just like releasing loads of works and you're free from stress and that's what makes someone retire for real. Look at the ultra rich people, they have all the means to retire and stop working and spend all their riches until they're dead but they don't just stop, they keep working on but with lesser loads and tasks. Maybe, that's what really retirement is.
