Help Grandpa finish his slightly exaggerated life story by dragging the correct verbs into the blanks.

"When I was twenty, I could lift a desk with one hand! But these days, I can't even lift this cup."

"When I was twenty, I could lift a car with one hand!"

We use could to talk about a general ability in the past.

"But these days, I can't even open this jar of pickles."

We use can't (or cannot) to talk about an inability in the present. Because Grandpa is talking about "these days," we use the present tense.
