Interesting to find this research! good job!

Why so? ProtonVPN explained the situation quite clearly though I don't understand why you wouldn't trust NordVPN. Just because they are advertising? Or 'military-grade encryption'? They aren't misleading really, even if it is a marketing gimmick. And who runs it... Well, it is a caveat with most of the VPNs. Because of the delicate nature of them (cybersecurity service, various jurisdictions and such), you don't really know. It is a matter of trust, more than anything. I know that I trust them more than my ISP, that's for sure.

Running your own VPN doesn't really anonymize you though. And like you said, depends what you want from the VPN really.

On age and your activities during the day. Insomnia and lack of sleep are really bad.

This is really interesting, though I can't see it exploited very widely in everyday use.
