Are disabilities like this, or disabilities in general, more prominent in little people? I worked with a person who was about your age and they were in a wheelchair, and they went on long term disability within 5 years.

But don’t most parts of the earth have some obvious sign of humans? I would point to plastics as a particular sign.

The Fermi Paradox isn’t just about us finding signs of intelligent life. It also encompasses the idea one of those intelligences would expand their civilization to other star systems, and if that was viable they would continue to do so exponentially. By this time they should have colonized the whole galaxy. Thus the use of a Great Filter that prevents this.
