Some personal comments are given on some of the exciting interfaces between
the physics of HERA and the LHC. These include the quantitative understanding
of perturbative QCD, the possible emergence of saturation phenomena and the
Colour-Glass Condensate at small x and large Q^2, the link between forward
physics and ultra-high-energy cosmic rays, and new LHC opportunities opened up
by the discovery of rapidity-gap events at HERA, including the search for new
physics such as Higgs bosons in double-diffraction events.Comment: 14 pages and 9 figures latex using cernrep.cls and mcite.sty,
