Do any of you think you are too old for speech therapy or too old to improve your speech?

Do any of you think you are too old for speech therapy or too old to improve your speech? I've had a stammer/stutter on and off for most of my life. Most of the time it doesn't bother me in the slightest but 2 years ago I started a new job and it went downhill fast. I kept this to myself as I thought there was no advantage to talking about it. I thought there was nothing I could do. I thought I was too old to change my speech patterns. Eventually I felt like I hit rock bottom. I told a family member and I agreed to try speech therapy. she basically told me that people of any age with any level of stammer can improve. I improved drastically since then and it without trying to go over the top here, it was life changing. Soooo, basically the point of this post is that if your speech is having a huge effect on your life, contact a speech therapist! You have got nothing to lose!
