A team of American scientists may have found a way to reverse the ageing process.
They fed diet supplements, usually found in health food shops, to elderly rats, which
were then tested for memory and stamina. The animals tended to display more active
behaviour after taking the supplements, and generally their memory improved. In
addition, their appearance became rather more youthful and their appetite increased.
The researchers believe that this experiment is quite a clear indication of how the
problems of old age may be overcome. They claim that in a few years’ time many people
may be able to look forward to a fairly long and active retirement.
