This was an amazing help last year when my wife was had really bad PTSD symptoms from a medical crisis she had. We walked 3+ miles almost every day last fall through January. She started getting better around then, and we started shortening our walks to 1 mile a day throughout the spring.
Now it's over 100ยฐF every single day and we are stuck inside for at least another month. Luckily she's doing well these days, but I do miss our walks.
