The hot components of Algol-type binaries which are main-sequence stars generally have positions in the H-R diagram which correspond to their masses. Consequently they look like old main-sequence stars. However the real age of a system in which transfer and loss of matter has occurred may be greater than the apparent age of the most massive component. Some evolved binaries have been selected which, under reasonable hypotheses, are estimated to be in this situation. The relation to the blue-straggler problem is examined.
