Old man pro tip: Turn mostly vegetarian and start exercising in your 40s, you'll avoid diabetes, high blood pressure, and erectile dysfunction, all things you don't want.
Another Old man (mid-60's, closer to 70 than 60)
Meat eater + vegs - higher than normal testosterone level (for my age)
Erectile Dysfunction - Viagra works great
Diabetes: had for 55+ years, still have all my parts
High Blood Pressure: since my 30's (not supposed to take Viagra with my meds, but kill me if I can't do the dirty deed)
3 out of the 4 and still functioning like a 40 year old, feel young and plan to be in the hobby at least another 20 years
