If you're asserting that the growth of hit point values has made PCs more durable... no, it hasn't. Damage values have grown at the same pace. A 4th-level AD&D fighter averages 22 hit points, and an AD&D orc attacks for an average 4.5 damage. A 4th-level Next fighter with a (rather generous) 16 Con has 40 hit points, and a Next orc attacks for 8 damage. The Next numbers are bigger, but the ratio is virtually identical, and the ratio is what matters....was referring to today's players not having to think, Dausuul. Not so much the growth of hit points. I'll give you a moment to re-read.
If you're saying something else about hit points, I'm at a loss for what it might be.
And if you aren't talking about hit points at all, what are you doing in this thread?
