 write a weekly science question and answer column 
for the San Jose Mercury News, and I have some pesky 
questions that I have not been able to find reliable, 
authoritative answers for, most likely because these 
aren't hot subjects for research, so even experts in 
the various fields can only speculate. 

But I know from experience that there often are experts 
with reliable answers hiding out there, and the trick is 
finding them. I would appreciate any tips on who to call 
who may be able to help me find answers to these questions.

1. Why do joints ache when the weather is bad? 
Is it dampness or atmospheric pressure that triggers the 
aching, and how does it do it?

2. Why do you often sneeze when you look at the sun?

3. Why can't we tickle ourselves?

4. Why are moths attracted to light? 

I am not very expert on newsgroup discourse, and would 
appreciate it if anyone who wants to offer assistance could 
send their messages to my e mail address. 
I am on the Internet, and my address is barinaga@netcom.com

Thanks in advance,
Marcia Barinaga
