That's ridiculous.

walking is a nice way to experience your surroundings at a gentle pace that might allow for surprising, inspiring interactions or discoveries

Only maybe in US, more probably only in some weird micro bubble you live in. Otherwise all you write is false obscure projection. Maybe go outside more? Its pretty healthy also mentally
