The longest lifespan of a turtle is more than 170 years. Turtles live longer than other animals because they have longevity genes and a slower metabolism. The lifespan of a tortoise is related to the species and living conditions. The lifespan of domestic tortoises is generally about 15-20 years. Careful care and regular physical examinations can increase the lifespan of domestic tortoises.

Methods to increase the life span of turtles:

1. Reduce turtle illness. Observe the turtle's condition and treat it promptly if any signs appear. Colds and enteritis have a high mortality rate for turtles.

2. Breeding space. The breeding space must be at least 5 times the size of the turtle itself to be suitable for the turtle to live.

3. Breeding environment. Basic facilities such as balconies and shelters are the basic living conditions for turtles.

4. Healthy feeding. The turtle's digestion is very fragile, so do not feed too much high-fat food that cannot be digested. The digestion of turtles is related to temperature. The temperature and frequency of feeding should be considered. It is better to eat less than too much. Turtles are not afraid of being hungry or holding on.

5. Sunshine. For reptiles, sunlight can not only maintain body temperature, but also help digestion and improve body functions.
