Age should not be the deciding factor for assumed experience.

If two posters say the horse is jumping under it's shoulder (or whatever the terms were) and one poster is 60 , the other 23.
They are both right.
If the 23yr old posted it first they are wrong by you're standards.
If the 60yr old shows up and posts the same damn thing , they are right because they are older.

That kind of logic is so flawed. You take information that's given for what it is.
If it's a well thought out post then that's exactly what it is regardless of the posters age.
