A debt-to-GDP ratio of 60% is quite often noted as a prudential limit for developed countries. This suggests that crossing this limit will threaten fiscal sustainability. For developing and emerging economies, 40% is the suggested debt-to-GDP ratio that should not be breached on a long-term basis.
1 Telomerase is found in high levels in germline cells (egg and sperm) and stem cells. 2  In these cells telomere length is maintained after DNA replication and the cells do not show signs of ageing. 3  Telomerase is also found in high levels in cancer cells.
Telomeres act as the time-keepers for your DNA. As the cells in your body divide, your telomeres get shorter. The shorter your telomeres, the more you age. So the more often your cells divide, the older they behave and the more susceptible you are to age-related disease. New advances in telomere biology make. it possible for you to reprogram the aging.
