Are Entrepreneurs workaholics?

Simon Leung - a fellow linked inner - asked a pertinent question that hit a chord with me , and obviously quite a few others -

Are entrepreneurs workaholics? 
I find myself working 24/7, Simon says - eating , breathing and talking about my work - being obsessed! 

Of course that means tweeting, travelling, meeting, speaking, networking, continually selling, browsing, I phoning and I padding 

Are you an entrepreneur? Can you relate? Is this healthy? Is this Normal? 

Would love your comments!
