Hot water runs thin, hot water is being choked off?

Our hot water pipes have less and less water coming out.

The house is more than 20 years old.
I believe the pipes are copper.
1) Could they be choked by lime deposits?
2) if that is so, what if anything, can we do about it?
The sink faucet that is presumed to be upstream of the tub faucet runs well for a sink.
This is california, there are no plumbing or tanks in the attic.
The tub is on the second floor.
