Full Spectrum Daylight Light Bulbs

In the past couple of years "daylight" light bulbs have started to be generally sold. These are bulbs which have less yellow light and thus are closer to daylight. The Solux company website persuasively and toughly claims that its competitors all do a bad job of replicating sunlight, as the diagram here shows. If they are being truthful, their own $8 bulb is far better, though it needs a two-prong, non-standard fixture. I wonder whether any normal-fixture bulbs are better than the Reveal brand?

Nicotine Prevents Senility?

From Wikipedia:
With regard to neurological diseases, a large body of evidence suggests that the risks of Parkinson's disease or Alzheimer's disease might be twice as high for non-smokers than for smokers.[26] Many such papers regarding Alzheimer's disease[27] and Parkinson's Disease[28] have been published.
