One issue you bring up, age--60! Some say it's the new 40! I held on to a combover for at least 12-15 years longer than I should have--cleaned up at 62.
Now, you're still young since you say you're interested in sports and activities. W/o a picture it's hard to say, but almost everyone I've ever seen transform from thinning bald to sly looks younger--most of the more "mature" guys here, including myself, can attest to the fact people all say a guy looks younger--NICE. Rugs are rugs--everyone knows you wear it--it's a fact. Getting rid of it will save you money & because of the economy we're probably going to have to work a little longer than we may have planned, you won't get your full SS benefits until 66 and the best return until you're 70. So adopting a style that emphasized your physical condition, and Sly does that, is to your economic benefit. $$$ talks, rugs don't. Think about the economic benefits--then experience the freedom. Shave it, sooner rather than later, you're missing the rush of Sly.
