All I meant was that if higher NAD levels make cancer spread faster, then that suggests a reason why the NAD level decreases as we age. That doesn't imply anything about whether higher NAD levels actually have that effect, and I thought it was reasonably clear from my comment that this was the first I was hearing about it. So...since you claim to be familiar with actual data, I suppose you can link a source or two supporting your claim? The person I replied to linked a paper in Frontiers in Oncology, and presumably its authors and reviewers did "actual real analysis of this data."
