Is Your Butthole Good for Absorbing Things?

Sunbathing was a fad, but if you Google what whole sunbathing is. A mere 30 seconds of sunlight on your butthole allows you to absorb more vital energy than an entire day in the sun wearing your clothes and or prayer. It's weird to me that like the rectum is where like garbage waste is expelled. Why would it also be a good absorber of things? Well, it's because they tried standing in the sun with their mouth open,. So they turned to the only other hole in the body. Is it for ostriches? Is it an ostrich development that we are we ostrich?
