Yes, now i realised it's very bad for my health and i had some lung and heart problems. been smoking for 4 years actually day after day. So now i decided to quit this habit starting from the next week and by starting going to the gym, cause i need to get my stamina and strenght a little bit and to get that nicotine out of my system. So if i want to, lets say have a career as a karate fighter, wouldnt it be late to start aged 19? Im not saying i want to be the best but im really excited about this sport and i want to get started.
