Yes, I still use bicycles (and I use them a lot). Recently I took a bicycle trip with some friends to a nearby town. The trip lasted about 3 hours. It was a bit exhausting, but it was well worth it. The benefits of using a bike range from improving the lifestyle and making some good savings.
Yes I like to go to the supermarket and buy groceries on my bike,and have a front basket and throw my backpack in it after I fill it up. Make sure you have a basket though,because it makes shopping really easy(and saves your back). I like to stop at the park and walk or run as well,so I get some extra exercise some times. This is easy to do because where I live, their is plenty of grass on the sides of the road to ride on,and I like to stay off the road most of the time.
