Let's say you're 65; there's Alzheimer's in your family, so you've likely inherited a gene or two that tips your scale arm a bit; you've been burning the candle at both ends for years; you love bacon; and you don't run unless someone's chasing you.
Imaginem que teniu 65 anys; i teniu Alzheimer a la família. Algun gen heu pogut heretar i pot desviar la balança una mica, fa anys que us excediu; us encanta la cansalada; i només correu quan us persegueixen.
