In the city, it’s much more difficult to find patches of sunlight due to the tall buildings. However, I find that walking by the river provides an open space where I can catch the most sunlight no matter the time of day.
More sun, more joy
I think the reason why people on the West Coast are much more easy-going and joyful is because of the amount of sunlight they get year round. Here in Philadelphia, there are much more cloudy days than sunny days during the winter months. Because of this, I find people are generally much more irritable and not as happy.
