Help for seniors!! (Geez...what did I come into the kitchen for?)

[Pharmboy]

There’s hope for old Freepers, ping...

My water is tasting funny.

What did Congress vote on last Saturday?

[maeng]

Nah! Hussein will never let this be wasted on us old people.

Its interesting what we remember. I have vivid memories of things from when I was little more than a toddler but have to think about what I did yesterday.

[razorback-bert]

I will bet that Alexandra would stay in my memory, well at least for that weekend.

[Pharmboy]

Indeed...becasue of that well-known phenomenon, neuroscientists have long suspected that short- and long-term memories form under different biologic circumstances.

I still remember my Mom breastfeeding my Sister. I was three years old at the time. Yet I have trouble remembering some people’s names that I met a week ago.

[Pharmboy]

While Alexandra is not a classic Swedish beauty, she’s got that Mona Lisa thingy going on with that smile. Yep...late nights in the lab with her around wouldn’t be that bad.

C2H5OH added to my water does the trick for me.

[agere_contra]

Did I fall asleep?

For a little while.

Not too obscure I hope!

...they were able to switch on and off the animals’ ability to form lasting memories by adding a substance to their drinking water.

Around here, we call that substance bourbon.

I have often pondered this. My late father-in-law remembered in his 90s the names of all of the students in his 6th grade class. He remembered in vivid detail many, many events from his life. I suspect that we retain those childhood memories so well because they were stored when all of the equipment was newer and had not been battered much. I put that facetiously, but I am sure there is some biochemical and neurological analogy.

Always astounding is the way a particular odor can take you back to a moment far, far in the past. For example, whenever I smell an orange, I think of childhood Christmases because we always had an orange in our stockings.

[cripplecreek]

I know that smell is pretty closely tied to memory. The sight of an old shotgun shell laying on the ground brings the smell back in a big hurry.

. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water.

Another take on the "it must be something in the water" description of Washington politicians.

BTTT

(I was going to write something clever but I forgot what it was.)

[wastedyears]

She’s pretty cute.
