How come Stephen Hawking is still alive and kicking (aged 69) even though sufferers of ALS usually succumb in their early 30's?

Most ALS suffers die when their motor neurons degenerate to the extent that they can't carry out essential bodily functions such as breathing ~~and digestion~~. Stephen Hawking's ALS isn't as progressive and has only had neuro degenerative effects on his muscular side rather than the **respiratory side he needs to live.**
