Why talk about half-life and quarter-life here instead of full-life (which I guess is around 18-24 hours)? Having less than a quarter of caffein in your system

Why talk about half-life and quarter-life here instead of full-life (which I guess is around 18-24 hours)? Having less than a quarter of caffein in your system does not impact your sleep?
- amalcon 5y agoIt's an exponential decay, so full-life is not really a coherent concept. Detectable (but unnoticeable) levels will persist for quite some time and undetectable levels will persist for a bit after that.
