Ha , by the time I reach 75 in forty odd years time, i should be able to have any body part I want, as long as the brain is good, ill live to 150 at least!
And yes, if i could afford it, why not. 75% chance of improvement is also 100% greater than not doing anything at all!
Dont knock the rich as well, they pay more taxes than the poor by default because they have more, generally they employ people as well keeping families fed, use less of the tax system as they have no need for benefits, keep technology progressing as they can afford to be early adopters.
Its mostly jealousy that causes rich bashing.
And just because your body is old, doesn't mean that you shouldn't try improve your quality of life if you can!
Speaking to many old people, they don't think old in their heads, we all stay young in our minds if we want!
Its just jelousy when people have a go at the rich!
