Yes... but shit, I have given up everything else, ie. coca cola by the bucket load, smokes, rarely alcohol... gotta die of something. Even those who are fitness fanatics, you could say are addicted to fitness, which is bad in itself and has killed lots of people, yet people don't see fitness as a bad thing, yet it can if abused.

Everything can be abused, but I believe it has to do with the severity off which counts a lot. If someone says to me they smoke or drink alcohol all day, that is bad... but if they drink tea, coffee, water, cordial, etc all day, that is far better than smoking or alcohol IMHO.
