Sports are often an important part of life for some, and many of them want a partner willing to sit in the bleachers and cheer on their team. It could be a difficult jump for someone previously uninterested in sports, but coming together while attending the game could be an achievement through finding an interest they can share. Many people love statistical information, so adding that information into the mix could make cheering for a particular team a fun opportunity for both of them.
Many people uninvolved in any part of watching sporting events often conclude it is nothing more than a physical performance, but passionate team supports know that is not the whole truth. They can see and share the planning, and precision that goes into melding a team, and being able to share it on the level of an intellectual exercise could create interest in their spouse. Attending the local sports arena on a regular basis could become yet one more way for a couple to spend time together.
