London - They say that opposites attract. But when it comes to alcohol, many of us seem to end up with a partner who shares our drinking habits.
Now scientists think they may have discovered why – and it’s down to our genes.
Some people have a mutation in their DNA that makes them enjoy alcohol. And if you have it, your partner is more likely to have it too.
This could help to explain why drinkers tend to get together with other drinkers and couples often seem to drink similar amounts.
