I had sent a link to this to PF earlier in the day!

I don't have a scientific mind & I leave it to the scientists to question why we have so few genes (er, I didn't know we only had a few -- ya see? I have no clue!). If there is life on other planets, I hope they're treating theirs better than we are ours, etc. I'm too hippie, Mother Earth to ponder the big questions.

One that did stand out for me was "Is an HIV vaccine feasible?" because of my ex.
