My Grandad smoked from age 12 until he was 75 and he just quit the day he retired at 75. Said he didn’t want to be smoking while he was not working anymore and being more sedentary. He’s not touched a cig since, didn’t use any gum or patches and hasn’t had an e-cig. He smoked 20 a day for about 50 years. If he can quit ANYBODY can!
