If this courageous and generous fan can help Rush by this extremely kind and loving offer; he and Rush better get to it because at age 70 one can no longer receive an organ transplant in the USA. Rush will be seventy on 1/12/2021.
I know this because I am precisely 26,406 days old (about 72.25 years) and am aware of this "extreme age" restriction that our brilliant government critters have instituted, at 70 one is only useful to the trash heap.
I harken back to the Obamacare "death panel".
They can have whatever needs to be done outside of the US. There are many countries that would accommodate Rush and a donor.
One of my coworkers in the office across the hall had a second liver transplant after age 72. There may be arbitrary rules for medicare patients, but if you have other resources, those rules wouldn’t apply.
How old was Dick Cheney when he got his transplant?
