With the property values in Palo Alto, I almost expect a dude funded this study, just to boost a property value by a few million. Eg, one near Standford Hills or whatever.

(it does feel nice to walk in nature though)

There’s a general benefit to the SF Bay Area outside Palo Alto as each municipality, county, state, federal and open space organizations like the Midpeninsula Open Space District have been maintaining and increasing public parks under their respective jurisdictions open to most all, and free to non drivers. Only my personal experience but it’s a sharp contrast to Texas where 95 percent of land is privately owned and access to open space is much more limited by comparison. I had a few favorite parks in Texas and new ones since I left 30 years ago are close to nil - there’s still a bit extra you can pay the owner for access.

This is not a snipe, please go outside. Take some deep breaths, be around some flora, and fauna. This kind of cynical non-sequitur tells me you're looking for something to be frustrated at.
