How many emails per day do you receive?

Today I notice that I have been spending a lot of time checking my emails. I decided to count all the emails that are purposeful to me. I counted around 40.

Is this too many, not enough, or should I spend some more time in the real world?

What are your thoughts?

Update: I just counted all my emails that I have received and got stored in my Thunderbird Inbox. Below are the stats.

I have received 9055 total emails between 14/03/2005 to 10/12/2009 It is 1733 days from the start date to the end date, end date included Or 4 years, 8 months, 27 days including the end date That is: 5.22 emails per day 36.57 per week

Still to many, or do you readers get more?
