I also have a good sense of direction. I’ve never been truly lost before. I also have perfect pitch and can identify any tone by its letter note (my desk fan is at work humming B-flat as I type this). To me it’s as easy as idenifying a color, yet very few people seem to have this ability. This ability also allows me to play songs by ear on various musical instruments.
I can do math in my head, up to adding or subtracting two 3- or even 4-digit numbers, and multiply two 2-digit numbers. Long division in my head is a challenge, but I can usually approximate with this.
