I used to have the same impression that there weren't many devs over 40, and if you found one, they were likely to be a little senile. I've now realized that this is more due to the corporate (or wanna be corporate) environments that I've worked in. Such environments really suck the life out of you and are rarely conducive to staying passionate about software development. My assumption is that people passionate about development don't stick around more than 5 years in these environments and either move to smaller startups or go independent soon after. I think .NET developers like myself almost exclusively see this type of environment in the jobs that demand our skill set. All the more reason why I'm focusing on learning Ruby, NoSQL, iOS, and Linux in my spare time.
