Love is blind. How blind?

As much blinding to make a 33 year old man marry a 104 year old woman.

104-yr-old bride for 'lovelorn' 33-yr-old

Excerpts...
// Age is no bar for love. This was proved when a 33-year-old man in Malaysia tied the knot with a 104-year-old woman, who had married 20 times before.
Muhamad Noor Che Musa married Wook Kundor in February saying their marriage was based on mutual love and care.
The ex-army serviceman from Kuala Berang in northern Malaysia felt the 71-year age gap will not pose any barrier to their relationship as after marrying Wook, he had found 'peace'.
"But this is Allah's will. My intention towards Wook is very sincere. I am not after her money as she is poor. Her only asset is her deep religious knowledge," he said.
"Through her, I can deepen my knowledge of the religion while at the same time help her master the Romanised script," he added. //

He could have adopted her as a mother and lavished the same amount of attention and affection. Couldn't he? What's idea behind this marriage? Is a marriage really necessary to proclaim love? Is a marriage necessary to validate his feelings towards this woman? Marriage is a man-made creation. What happened before that? Did man not express their love for a woman?
