Athleticism is very definitely age based and everyone's cliff is different. For me a hopeless specimen athletically went from slow to glacier slow at around age 32. The explosiveness begins to evaporate and there is no getting it back.I remember Alex Keath saying the same thing before having a steep nosedive
Could see maybe another 2 maybe 3 good years left in Lobb but I feel like 4 is just a bit fanciful
