What are your thoughts on Nicotine competing with NAD+ in cells and thereby reducing SIRT1? Could this be one of the causes for reduced lifespan in smokers? If so, would that also affect lifespan for people smoking e-cigarettes?
Thanks for looking to reach out! I try to reply to every single email I get (really!), but sometimes it takes a little while or some messages just fall through the cracks, usually by accident.
I give a special increased priority to my supporters who message me through Patreon, so please consider making use of their messaging system by pledging a small amount to support my website.
