[00:01.80]4 Immortality has been a constant theme [00:04.43]in futurology. [00:05.34]Actually, we do now know how to extend life- [00:08.55]by eating less and exercising more. [00:10.99]Even so, Californian cryogenics super- [00:13.97]salesmen have persuaded some people [00:16.53]to part with vast sums of money on a promise [00:19.60]that will defrost them when "the time is right" [00:22.59]But since we haven't yet even perfected [00:24.57]freezing strawberries, [00:26.20]these poor deluded souls may be nothing [00:28.66]more than mucky puddles by 2052. [00:31.98]As for transport, the reason we aren't [00:34.47]all buzzing around in our own mini- [00:36.42]planes has quite a lot to do with the fact [00:39.01]that nobody thought about what would happen [00:41.09]when everyone wanted one. [00:42.88]Were they going to be stacked high [00:44.35]above our streets, [00:45.79]stuck in an endless holding pattern [00:47.92]while we desperately tried to do our shopping? [00:49.53]
