Sorry, kingshockey, but if you are over 45 and have been instinctively self-medicating with nicotine then it is a very bad idea to stop taking the drug as long as you are alive.
There is a current fad among vapers to reduce nicotine levels. This is confirmed when "Jacques le Houezec mentions that there is currently a
movement among e-liquid manufacturers and among the vapers, themselves, to reduce nicotine strength. The obvious issue is to get exposed to more toxins but the tobacco expert recalls that
the risk is also to relapse into smoking."

It seems a large number of vapers are also lunatic ANTZs and will tolerate no nicotine which is crazy because it is a wonder drug that is inexpensive and readily available.
From Discover magazine, "If dozens of human and animal studies published over the past six years are borne out by large clinical trials, nicotine [...] may prove to be a weirdly, improbably effective drug for relieving or preventing a variety of neurological disorders, including Parkinson’s disease, mild cognitive impairment (MCI), Tourette’s and schizophrenia. It might even improve attention and focus enough to qualify as a cognitive enhancer. And, oh yeah, it’s long been associated with weight loss, with few known safety risks. "
And one risk of not using nicotine has been well-known for more than fifty years, "The first hint of nicotine’s curious benefits came from a study published in 1966 by Harold Kahn, an epidemiologist at the National Institutes of Health. Using health insurance data on 293,658 veterans who had served in the U.S. military between 1917 and 1940 [...] one oddball jumped out: Death due to Parkinson’s disease occurred at least three times as often in nonsmokers as in smokers."

In other words if you stop taking nicotine, at the very least, you will triple your chances of dying from Parkinson's.
If you stop listening to the bad advice of ANTZ lunatics and keep taking nicotine you will keep more of your 'marbles' and live for a longer period of time, guaranteed.
