re: thread about "mixing up words" / spoonerisms

i started mixing two words up frequently about 4 months ago(for reference, i will be 38 in march).i only do it when speaking and had found it to initially be quite comical.upon a recent trip to the doc for a checkup i happened to mention it and he said, how are your thiamin / b1 intakes?i said, umm, no clue. so he did blood work and sure enough my levels were extremely low.these nutrients are essential for memory and neurological function.i started supplements 3 weeks ago and havent had an incident since.just thought i would share.
