i think walks on the beach show love and that people are dating
that's true. Most people you find there are couples 
but its very relaxing and one can walk for a very long distance
It can also drive away stress
when one breath in deeply and relax in that environment
you also get to enjoy the cold breeze 
its also great taking the family to the beach once in a while
I like spending like more than 3 days there
i love the gorgeous sunsets and the soft sand feeling
I can relate that with my personal experience
