ALMOST EVERYONE WILL BE ABLE TO CLIMB KILIMANJARO

Switzerland is already heavily promoting e-bike tours through the mountains – and it’s a trend that Dr Yeoman sees continuing. “Generally, adventure will get easier,” he says. “There will be more e-bike routes like those in Switzerland, but there will also be more extreme developments. With so much work being done on exoskeletons, in 25 years the unfit or even infirm will be able to compete in a desert ultramarathon or climb Mount Kilimanjaro.”
