As it happened, the first three major advances in my life--and I will list all the advances here-- 1. shoe-tying 2. pulling up on Xs 3. steadying hand against sneaker when tying 4. brushing tongue as well as teeth 5. putting on deodorant after I was fully dressed 6. discovering that sweeping was fun 7. ordering a rubber stamp with my address on it to make billpaying more efficient 8. deciding that brain cells ought to die --have to do with shoe-tying, but I don't think that this fact is very unusual.
