Anyone Else Add A Brake To Their Fixed Gear Bike?

I tried riding fixed a few times, I just can't do the downhills, I switched to singlespeed ( I ride mostly road) and have both front and rear brakes.
My vintage Falcon Black Diamond fixie was customized by a bike guru, who geared it for mostly flatland riding (urban). Although I only used it in emergencies, there is a custom front brake added to it.
All of my bikes have front and rear breaks, its a must for me, you can never be too safe with just one. Besides, how can anyone ride without brakes? Whenever you buy a bike it has one.
