Yann Martel said this quote

Ageing is not easy, Sennhora Castro. It's a terrible, incurable pathology. And great love is another pathology. It starts well. It's a most desirable disease. One wouldn't want to do without it. It's like yeast that corrupts the juice of grapes. One loves, one loves, one persists in loving-the incubation period can be very long- and then, with death, comes the heart break. Love must always meet its unwanted end.
