Some days it's higher if I'm overheated, and some days it's a little lower like 67, but in general? It's around 70, for about a decade now. When I was younger (20s) it was around 80. And I was literally running marathons.
My HR can hit 195 when I'm running hard, but it drops super fast when I stop, so, the cardiologist said it was totally fine.
Yeah, it's just one metric that often correlates with fitness, but not 100%. I'm the 30s/40s poster and I think mine was always naturally low, but did get much lower once I started training more seriously (and goes up when I slack off for a few months).
Another point that came up in the thread - RHR actually has a definition from the watches/medical community. It's not just randomly measuring your HR sitting down during the day. I'm not going to bother looking up the specifics, but you can probably get a quick overview on a google search.
