V laborat\u00f3riu sledovali 81 rybiek a vytvorili miliardy videoz\u00e1znamov, z ktor\u00fdch analyzovali pohyb, postoj, odpo\u010dinok a r\u00fdchlos\u0165.

Aj ke\u010f mali ryby takmer identick\u00e9 \u0161tartovacie podmienky a podobn\u00fa genetiku, ich \u017eivotn\u00e9 cesty sa dramaticky rozch\u00e1dzali. To nazna\u010duje, \u017ee starnutie nie je len naprogramovan\u00e9 v DNA, ale vznik\u00e1 z drobn\u00fdch kumulat\u00edvnych zmien v tom, ako organizmus funguje a reaguje na prostredie.

Starnutie neprebieha plynulo. Ryby pre\u0161li dvoma a\u017e \u0161iestimi r\u00fdchlymi zmenami spr\u00e1vania, ka\u017ed\u00e1 trvala p\u00e1r dn\u00ed, medzi nimi nasledovali stabiln\u00e9 obdobia trvaj\u00face t\u00fd\u017edne.<\/p>\n
