Plus ten years minus five

it would make sense for me to do it because i imagine the quality of the last five years of my life are going to be much poorer than the rest (at least physically my body will be shot)

So then every ten years of this 'perfect life', 5 years would be subtracted from your life span? Or is it just one set of 'perfect ten years'

That is a very tempting deal..quality over quantity. Whenever I sense these 10 perfect consecutive years started I would think it be easier to find true love and rush to make a family hmm maybe play the lottery since my luck stat might be maxed xD that way my kids future are secure. I'm sure I would notice a perfect year right away. So my answer is yes.
