Newbie to group

Hi, i am new to this group chat so here goes, im male, 45, a couple of stone overweight and had a heart attack 4 and a half years ago. I did stop smoking and became quite fit losing 3 stone during lockdown but this year i have put the weight back on and started smoking again. I have now been 3 days off the cigarettes and plan to do more regarding my eating and exercise in the next couple of weeks.
