It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.

Ageing is very exciting. But if I didn't work on ageing, I'd want to work on the brain. There are really cool techniques you can use now. And bioinformatics. The methods you can use for comparing large data sets - that's so powerful.

Imagine that: If you could change one of the genes in an experiment, an aging gene, maybe you could slow down aging and extend lifespan.

Maybe one day we will be able to take a pill that keeps us young and healthy much longer. I believe in my heart that this will happen.
