I'm heterochromic (my eyes are 2 different colors).
I failed 4th and 7th grade basic math...now my synthesis algorithms are reviewed and confirmed at MIT (1+1≠2).
I've had chronic insomnia (off an on) for about 4 years...which gives me a lot of time to get stuff done but never the ability to remember how I did it or why I thought it necessary to write it all down on my bedsheets.
I use those old 3.25" floppy disks daily.
