It seems that lithium, MAOs, tricyclic and other medications helped depression before prozac and other selective seratonin re-uptake inhibitors (SSRIs) came along. If these other medications worked before the SSRIs, then why is seratonin regulation the only answer to depression?

Everyone I know are so excited that Mars will be coming up very close to us again. Yes we all know it once hap pend in 2003. They didn't think it would happen again for another 60, 000 years, but it looks like it happening right now.
On the other hand when I asked the question of who was excited about it many people called me an idiot basically. What's going on? Mars is always close this time of year, but they say it's going to be so close it will be visible to the naked eye. Tennis ball size I hear.

Three guys have to share a room in a hotel. They go to the front desk and are told that the cost is $30. They all give up $10 a piece and go to their room. After a while, the front desk clerk is told that the room should only have been $25. So he gives the bellhop five $1-bills and asks him to return them to the three gentlemen. On his way to the room, the bellhop decides that, rather then trying to split the $5 between the three men, he would give them $1 each and he would keep $2. So, the men all end up paying $9/each for a total of $27 and the bellhop has $2 which adds up to $29. Where is the other dollar? ;-)
