Knocked me a bit sideways this one. As has been said he lived a healthy life. He only ran the London marathon 5 weeks ago too. I'm a keen runner, look after myself and am 3 years younger and you think stuff like won't happen to you.
I'll be honest I really disliked him as a player (which probably meant he was doing all the right things!), but I have mates in the coaching world who know him personally and all of them to a man held him in really, really high regard. His efforts at Orient are a great legacy to leave.
RIP Justin and condolences to your family
