Even without improvements to memory or cognition, biking is a massive stress reliever in my experience. After a 40 mile trip I have found it basically impossible to worry and not be in a generally good mood.
Unfortunately the Bay Area has few great options compared with other regions I’ve lived if you are looking for long, dedicated routes (no sharing with cars) without cross traffic.
THe bay area is the best for cycling in the US. Unfortunately I have left but it really is the best. Category 2 climb a few miles away and bike lane on most roads is hard to beat by US standards.
