My friend, an owner of the gym i go to, is 55 years old. Since he was 15 years old, he has been training, and in his youth he competed in several local competitions. His back and arms are amazing. His father on the contrary, 78 years old, is a cabinet maker and carpenter since his youth. One weekend, my friend, his father, and myself started building an outdoor gym area–just the walls and the roof. While my friend and I struggled with the beams for the roof together, his father was walking up the ladder with beam in hand. Amazing! Technique and hybrid-strength. On the other hand, I’m 31 years old 174 lbs, 6 ft tall. I can carry a large two-door fridge on my back up a flight of steps but I can’t squat more than 10 reps of 175 lbs free weight.
"This volume provides a basic understanding of the definitional and diagnostic differences among use, abuse, and disorders. It describes in great detail the characteristics, etiology, and commonalities among all of these syndromes. It also describes a variety of addictive behaviors, both behavioral- and substance-based, and their similarities and differences. It is part of an exceptional, comprehensive series that should serve as a reference for all involved in the field."-- , January 3, 2014

So, all that being said, should you buy it? Well, do you have the need? The need for speed? If so, then you’re not going to find a faster camera out there. The A9 costs $4,500 for the body alone. While that’s cheaper than the Canon 1DX or the Nikon D5, unless you really, really need to be able to shoot fast-moving objects, then you’re probably better off with one of Sony’s A7 series cameras (get the mark II versions). These are also full-frame, mirrorless cameras that take excellent pics, they just aren’t as fast. But if you’re a budding sports photographer and you aren’t already heavily invested in glass from another manufacturer, the Sony A9 is incredible in so many ways.
