question: My name is Ashim Nayek residing at Durgapur and I have two children and my elder son aged 17 year who is very absentminded and can not concentrate in his academic studies normally. His patience is very little and erratic in nature. He did very worse in his recent school final exam ( Class X exam.) due to his unmindful nature and he also involve himself in smoking  cigarette seperately. He frequently behave very eratic with his perents. So please advice me how I tackle my son in coming days. thaking you, ASHIM NAYEK VILLAGE AND POST.- GOPINATHPUR DURGAPUR - 713211 DIST.- BURDWAN WEST BENGAL MOBILE : 0000.
