How do you push headrest all the way down?

There is a black ring right at the seat and you push in on the side of that and it will let the headrest go down.

you stretch legs and keep practicing everyday until you can do it but you got to love it get in the splits form and bounce up and down until that's as far as you can go and stay that way for 10...

This is a safety feature.

Thers's something in the back of your throat that they touch and it feels so good to them

I had the same problem with my 95 and all it needed was lubrication worked into it. Spray a lubricant into the latch assy and apply grease to the hook portion of the latch that contacts the hood.
