Hello. I just wanted to ask. Is it normal to take deep breath every 1 or 2 minutes. I am overweight and smoker who's trying to quit but last couple monts I'm noticing that I need to take deep breath very often and then sometimes not . So I would like to ask how often slim and fit person need to take deep breath? Is it individual? Lately I'm worrying if it's not something bad with hearth or lungs or if weight and smoking causing this.

Thanks.
