in my case yes, for most of these dudes, no. hehhhh
And yea 31 is meta age. I don't think Long life affects int as in raises it though. I don't think it lowers it. I think once you go past the age where your int will fall that it will not 'soften' that, either, so actually it probably does not affect it. Can check through the char creator. I can check for ya!
Edit: WOW you can break caps at age 70! 109 INT 121 PSYCHE for pure SHEEV. MARK THAT DOWN. V nice. NEW META?!?!?!?!?!
Edit2: but no way you can really get enough att pts to use it, imo. The speed is legit tho.
