The physics underlying the fall and eventual rise in various total
cross-sections at high energies has been investigated over a decade using a
model based on the Bloch-Nordsieck resummation in QCD. Here a brief review of
our latest results is presented and comparison made with experimental data on
pp, γproton and γγ total cross-sections.Comment: Presented by G. Pancheri at ISMD04, Sonoma State University. Under
