Skill decay
The only skill that decays in BT is stamina - this starts to slowly decrease, beginning at age 33.
A very old player may still be an exceptional batsman, but his stamina will end up so low that he will probably be too tired to play after even one ball and his average performance (and fitness recovery rate) will be terrible. There is no 'retirement age' for players, they live on until they are fired.
NB. Further research is being done in this area. The following info is theory only, based on early indications.
Stamina decay rate
The rate of stamina decay seems to be fairly linear in relation to age:
- 33 years old = stamina decays 1 level every 16 weeks (approx)
- 34 years old = stamina decays 1 level every 13 weeks (approx)
- 35 years old = stamina decays 1 level every 10 weeks (approx)
- 36 years old = stamina decays 1 level every 7 weeks (approx)
- 37 years old = stamina decays 1 level every 4 weeks (approx)
- 38 years old = stamina decays 1 level every week (approx)

NB. The negative values indicate a net loss - meaning the player is losing stamina overall, even though he is being trained.
The 'weeks to increase one level' shows how long it will take his stamina level to increase, or decrease.
Eg. a value of -6.13 weeks means that even though he is receiving one stamina training net, he'll drop a level of stamina every 6 or 7 weeks.
