Hi @Dave3, thanks for sharing your note. It’s understandable that reading about later stages can raise a lot of worries. Fears about falls and about being there for your wife are certainly very valid too.
You’re not alone in having these thoughts, and others here may relate and share how they’ve approached similar concerns over time.
Regarding breathing, we have this page on lung health which may be useful to you: Lung health and Parkinson's | Parkinson's UK
And please remember our helpline is always here for you if you’d like to chat things through. We’re just a phone call away on freephone 0808 800 0303.
Sending you our warmest wishes
Parkinson’s UK Moderation Team
