Indeed, old young we all fly for the same reasons and provided the old guys pass the checks and the medicals they have as much right to the seat as the younger blokes next to them.
Perhaps if the younger blokes stopped thinking about 'me' all the time and listened to the old crusty bloke next to them they might learn a thing or two
These old blokes may not be as sharp as they used to be but in terms of experience, I'd rather them in the left seat making the calls in an emergency any day.
