| Yes, all these good changes took place. We live longer and became bigger. All these changes are due to a more comfortable life, vaccinations, etc. However, all this takes place under umbrella of comfort and all kind of service secured by technology. I do not suggest that technology is bad. I use it myself. This simply an observation. There are other research results, for example, mutations of old foes, such as TB bacteria; now we have high frequency of people susceptible to TB genetically; new bacteria are resistant to antibiotics and kill again. This technological umbrella would break or even become completely eliminated by drastic changes in the climate and then all mortality of the weak would go up. |
