Don't need mathematics
To know how much you're mine
Measure, off the scale
Got no acrobatics
To prove you're all I desire
All of the time

No, there ain't no mystery
101 biology
Feel my pulse react
When you look in my eyes
It's making me high, oh

All of your love
It ain't in a book
Sweet simplicity

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Only one that you need
Part of a love so deep
Know that you'll always be
All mine, all mine, all mine

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Only one that you need
Part of a love so deep
Know that you'll always be
All mine, all mine, all mine, all mine

All of your love
It ain't in a book
Sweet simplicity

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Only one that you need
Part of a love so deep
Know that you'll always be
All mine, all mine, all mine

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Chemistry, chemistry, chemistry, chemistry, chemistry, chemistry
All mine, all mine, all mine

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Only one that you need
Part of a love so deep
Know that you'll always be
All mine, all mine, all mine

Only one that you need
Part of a love so deep
Don't need a PhD
It's all in the chemistry
Only one that you need
Part of a love so deep
Know that you'll always be
All mine, all mine, all mine, all mine
