I certainly do know engineers in their 50s and 60s. However, one thing I notice is that they often feel "passed over" - not neccesarily in terms of salary etc, more in terms of decision making. I don't think it's that they are involved in less decisions than when they were in, say, their 30s, I think it's frustration that they see their peers who moved into management being involved in more decisions than them.
So yes, it is possible, but be careful what you wish for.
