If the tv is anything to go by they always seem to get decent looking women, the advent of decent LED technology means that night rides only shouldn't be a problem. Eternal life means that you'd outlast the 650b and 29er fashions, possibly. Maybe future rubber shortages might mean mtb in the future might be limited to 8" wheels.
Might be interesting to see if we all end up as either Muslims or atheists, or vampires....
Wish I could just get back to bloody sleep!!!
