Answer 2

The answer is Energy is transferred

There is always energy transferred every time we do a certain amount of work (even though we're not sure what we're doing like Doug) . The type of energy transfer that happen would be determined by the type of work he got.

For example, if the work that Doug donig requires physical work, his energy will be decreased. If the work that Doug doing absorb substance from external environment (such as eating foods), his energy willl be increased.

Nonetheless, there wil always be a transfer of energy in every work
