Thanks Rip, I'll always be there for my dad. And will push him into moderate training.
What's weird is he's supposedly had ALS for 4 years, but can still walk (definitely leg muscle wastage tho) but no change to voice or speech. Voice is still pretty robust.
He got J&J and Moderna jabs 4 years ago. I'm not saying it's that, but a physician (esp. in Boston) won't even consider that possibility. A second opinion wouldn't hurt IMO, but I'm not trying to give myself hopium.
